This is minor patch release with a few minor bug fixes and updates test expectations in anticipation of new R 4.0 defaults.
ggplotly() bug in axis tick translation (#1725, #1721).plot_mapbox() now correctly defaults to a scattermapbox trace (unless z is present, then it defaults to choroplethmapbox) (#1707).ggplotly() now correctly resolves overlapping axis tick text in coord_sf() (#1673).toWebGL() (#1569).treemap and image. The plotly.js release page has the full list of changes.add_image() function was added to make it easier to create image traces via raster objects.add_sf()/geom_sf() now correctly handle geometry columns that are named something other than "geometry" (#1659).event_data() gains support for the plotly_sunburstclick event (#1648)renderPlotly() (#1528).ggplotly() now positions the x-axis in the last column of a facet_wrap() properly (#1501).ggplotly() now handles geom_hline()/geom_vline() correctly in conjunction with coord_flip() (#1519).event_data() now correctly relays the key attribute for statistical traces (#1610).sunburst, waterfall, isosurface.hovertemplate attribute allows for finer-tuned control over tooltip text. See here for an example.title is now deprecated (but still works). Instead, use title = list(text = "title"). This change was made to support a new title placement API (e.g., title = list(text = "title", xanchor = "left")). Note that these changes are relevant for layout.title as well as layout.xaxis.title/layout.yaxis.title/etc.event argument of the event_data() function now supports the following events: plotly_selecting, plotly_brushed, plotly_brushing, plotly_restyle, plotly_legendclick, plotly_legenddoubleclick, plotly_clickannotation, plotly_afterplot, plotly_doubleclick, plotly_deselect, plotly_unhover. For examples, see plotly_example("shiny", "event_data"), plotly_example("shiny", "event_data_legends"), and plotly_example("shiny", "event_data_annotation"),event_register() and event_unregister() functions for declaring which events to transmit over the wire (i.e., from the browser to the shiny server). Events that are likely to have large overhead are not registered by default, so you’ll need to register these: plotly_selecting, plotly_unhover, plotly_restyle, plotly_legendclick, and plotly_legenddoubleclick.priority argument. By setting priority='event', the event is treated like a true event: any reactive expression using the event becomes invalidated (regardless of whether the input values has changed). For an example, see plotly_example("shiny", "event_priority").event_data() function now relays the (official plotly.js) customdata attribute in similar fashion to (unofficial) key attribute (#1423). Run plotly_example("shiny", "event_data") for an example.event_data("plotly_selected") is no longer too eager to clear. That is, it is no longer set to NULL when clicking on a plot after triggering the “plotly_selected” event (#1121) (#1122).orca() function now supports conversion of much larger figures (#1322) and works without a mapbox api token (#1314).orca_serve() function was added for efficient exporting of many plotly graphs. For examples, see help(orca_serve).orca() function gains new arguments more_args and ... for finer control over the underlying system commands.ggplotly() now respects horizontal alignment of ggplot2 titles (e.g., ggplotly(qplot(1:10) + ggtitle("A title") + theme(plot.title = element_text(hjust = 1)))).saveRDS() to save an object as an rds file and restore it on another machine with readRDS()). Note this object is dynamically linked to JavaScript libraries, so one should take care to use consistent versions of plotly when serializing and unserializing (#1376).style() function now supports “partial updates” (i.e. modification of a particular property of an object, rather than the entire object). For example, notice how the first plot retains the original marker shape (a square): p <- plot_ly(x = 1:10, y = 1:10, symbol = I(15)); subplot(style(p, marker.color = "red"), style(p, marker = list(color = "red"))) (#1342).method argument of plotlyProxyInvoke() gains support for a "reconfig" method. This makes it possible to modify just the configuration of a plot in a shiny app. For an example use, see plotly_example("shiny", "event_data_annotation").plotly_example() function will now attempt to open the source file(s) used to run the example. Set edit = FALSE to prevent the source file(s) from opening.config().stroke is specified, span now defaults to I(1). This results in a slightly narrower default span for some trace types (e.g., box, contour), but it also ensures the stroke is always visible when it’s relevant (e.g. plot_ly(x = 1:10, y = 1:10, stroke = I("black"))), making for a more consistent overall default (#1507).config() function no longer has a collaborate argument.cloud argument is now deprecated and will be removed in a future version. Use showSendToCloud instead.ggplotly() now translates title information to layout.title.text (instead of layout.title) and layout.title.font (instead of layout.titlefont)subplot() now works much better with annotations, images, and shapes:
xref/yref references an x/y axis these references are bumped accordingly (#1181).xref/yref references paper coordinates, these coordinates are updated accordingly (#1332).subplot() now repositions shapes with fixed height/width (i.e., xsizemode/ysizemode of "pixel") correctly (#1494).colorscale attribute now correctly handles a wider range of input values (#1432, #1485)color argument in plot_ly() now uses an evenly spaced grid of values instead of quantiles (#1308).size argument maps to marker.size, it now converts to an array of appropriate length (#1479).color and stroke arguments now work as expected for trace types with fillcolor but no fill attribute (e.g. box traces) (#1292).event_data() for heatmaps with atomic vectors for x/y/z is now correct (#1141).marker objects (#1351).ggplotly() colorbar would cause issues with hover behavior, which is now fixed (#1381).text attribute is no longer collapsed to a string when hoveron='fills+points' (#1448).layout.[x-y]axis.domain is no longer supplied a default when layout.grid is specified (#1427).api_create(), layout attributes are no longer incorrectly src-ified, which was causing inconsistencies in local/remote rendering of ggplotly() charts (#1197).plot_ly() specific improvementsscattergl to make it nearly feature complete with scatter, localization of text rendering (i.e., international translations), and six new trace types (cone, scatterpolar, scatterpolargl, splom, table, & violin)! See here for a complete list of plotly.js-specific improvements.plot_ly(), plot_mapbox(), and plot_geo() (via the new add_sf() function). See this blog post for an overview.stroke, strokes, alpha_stroke, span, and spans). For an overview, see the sf blog post linked to in the bullet point above and the new package demos (list all demos with demo(package = "plotly")).ggplotly() specific improvementsggplotly() now supports conversion of ggplot2’s geom_sf().ggplotly() about the relevant shiny output size via session$clientData. This ensures ggplotly() sizing is closer to ggplot2 sizing, even on window resize. For an example, run plotly_example("shiny", "ggplotly_sizing").TeX() function may be used to flag a character vector as LaTeX (#375). Use the new mathjax argument in config() to specify either external (mathjax="cdn") or local (mathjax="local") MathJaX. If "cdn", mathjax is loaded externally (meaning an internet connection is needed for TeX rendering). If "local", the PLOTLY_MATHJAX_PATH environment variable must be set to the location (a local file path) of MathJax. IMPORTANT: plotly uses SVG-based mathjax rendering which doesn’t play nicely with HTML-based rendering (e.g., rmarkdown documents and shiny apps). To leverage both types of rendering, you must <iframe> your plotly graph(s) into the larger document (see here for an rmarkdown example and here for a shiny example).persistent = TRUE in highlight(), but persistent = FALSE (the default) is now recommended since it allows one to switch between persistent/transient selection in the browser, rather than at the command line.highlight() function gains a debounce argument for throttling the rate at which on events may be fired. This is mainly useful for improving user experience when highlight(on = "plotly_hover") and mousing over relevant markers at a rapid rate (#1277)partial_bundle() function makes it easy to leverage partial bundles of plotly.js for reduced file sizes and faster render times.config() function gains a locale argument for easily changing localization defaults (#1270). This makes it possible localize date axes, and in some cases, modebar buttons (#1270).plot_geo() function gains a offline argument for rendering "scattergeo" traces with or without an internet connection (#356). Leveraging this argument requires the new plotlyGeoAssets package.plotly_example("shiny", "async").ggplotly(NULL, "message") and plotly_build(NULL, "message") now returns htmltools::div("message"), making it easier to relay messages in shiny when data isn’t yet ready to plot (#1116).animation_button() function gains a label argument, making it easier to control the label of an animation button generated through the frame API (#1205).highlight_key() function provides a wrapper around crosstalk::SharedData$new(), making it easier to teach others how to leverage SharedData objects with plotly and crosstalk.plot_ly() specific changesname attribute is now a “special plot_ly() argument” and behaves similar to split (it ensures a different trace for every unique value supplied). Although this leads to a breaking change (name was previously appended to an automatically generated trace name), it leads to a more flexible and transparent API. Those that wish to have the old behavior back should provide relevant mappings to the name attributes (e.g. plot_ly(mtcars, x = ~wt, y = ~mpg, color = ~factor(vs), name = "a") should become plot_ly(mtcars, x = ~wt, y = ~mpg, color = ~factor(vs), name = ~paste(vs, "\na")))color argument now maps to fillcolor, making it much easier to use polygon fills to encode data values (e.g., choropleth maps). For backwards-compatibilty reasons, when color maps to fillcolor, alpha defaults to 0.5 (instead of 1). For an example, plot_mapbox(mn_res, color = ~INDRESNAME) or plot_mapbox(mn_res, split = ~INDRESNAME, color = ~AREA, showlegend = FALSE, stroke = I("black")).color argument no longer automatically add "markers" to the mode attribute for scatter/scattergl trace types. Those who wish to have the old behavior back, should add "markers" to the mode explicity (e.g., change plot_ly(economics, x = ~pce, y = ~pop, color = ~as.numeric(date), mode = "lines") to plot_ly(economics, x = ~pce, y = ~pop, color = ~as.numeric(date), mode = "lines+markers")).size argument now informs a default error_[x/y].width (and span informs error_[x/y].thickness). Note you can override the default by specifying directly (e.g. plot_ly(x = 1:10, y = 1:10, size = I(10), error_x = list(value = 5, width = 0))).layout.showlegend now defaults to TRUE for a single pie trace. This is a more sensible default and matches pure plotly.js behavior.automargin = TRUE. The majority of the time this should make axis labels more readable, but may have un-intended consequences in some rare cases (#1252).elementId field is no longer populated, which fixes the “Ignoring explicitly provided widget ID” warning in shiny applications (#985).ggplotly() specific fixesheight/width that ggplotly() assumes is now more consistently correct in various context, but it also now requires access to one of the following devices: Cairo::Cairo(), png(), or jpg().ggplotly() was ignoring a specified height/width (#1190).ggplotly() now uses fixed heights for facet strips meaning that their height is still correct after a window resize (#1265).plot_ly() specific fixeslimits argument of colorbar() wasn’t being applied to line.color/line.cmin/line.cmax (#1236).legendgroup can now properly map data values (#1148).marker.size) are now always based on the area when marker.sizemode='area' (which is the default sizemode when using the size argument). Previously, traces with one just one value supplied to marker.size were being sized by their diameter (#1133).height/width via shiny reactive values, is now correct (#1068).add_*() no longer inherits crosstalk::SharedData key information when inherit = FALSE (#1242).plotlyProxy() and plotlyProxyInvoke() functions. For examples, see plotly_example("shiny", "proxy_relayout") and plotly_example("shiny", "proxy_mapbox"). Closes #580.plotly_example() function to make it easier to run shiny/rmarkdown examples included with the package under the inst/examples directory.schema() function now returns the plot schema (rather just printing it), making it easier to acquire/use values from the official plot schema. See help(schema) for an example. Fixes #1038.ggplotly() is no longer fixed to the device size inside RStudio. Fixes #1033.ArrayBuffer.isView(), which should fix rendering issues on plaforms that don’t have a typed array polyfill (e.g., RStudio on Windows). Fixes #1055.event_data("plotly_relayout") no longer fires NULL for any event. Fixes #1039.color with scattermapbox/scattergeo. Fixes #1038.marker.color as an array. Fixes #1084.coord_equal(), coord_fixed(), coord_map(), coord_quickmap()).geom_sf() and coord_sf().group2NA() function is now exported and its performance has been greatly improved thanks to the new data.table dependency. Essentially any geom conversion that reduces to a polygon/path should see speed improvements. Similarly, any plot_ly() graph that use group_by() in conjunction with add_lines(), add_paths(), add_segments(), etc will also see improvements, especially when there is a large number of groups. For details on the speed improvements, see #1022 and #996 (thanks @msummersgill).api_create() function gains a new fileopt argument, which is inspired from the fileopt argument in the (deprecated) plotly_POST() function (fixes #976). It currently supports to values: "new" and "overwrite". The default, "overwrite", will overwrite existing file(s) with a matching filename.filename argument in api_create() now accepts a character vector of length 2, the first string is used to name the plot, and the second is used to name the grid (i.e., data behind the plot).traces argument in the style() function now defaults to NULL (instead of 1). Meaning that, by default, supplied attributes now modify every trace (instead of the first one).coord_flip() (fixes #1012).api_create()), both the plot and the data behind the plot are private (fixes #976).api_create()) no longer creates multiple grids (fixes #1004).api_create() function should now create grid references for all data array attributes (fixes #1014).ggplotly() no longer opens an (off-screen) graphics device in RStudio for sizing. It will now correctly use the size of the viewer panel when querying the size of the graphics device.NULL for pie charts (fixes #1002)demo(package = "plotly"). For a more comprehensive overview, see https://cpsievert.github.io/plotly_book/linking-views-without-shiny.html. For some more complex examples, see https://cpsievert.github.io/pedestrians/highlight() function for configuring selection modes/sequences/options.help(animation). For a more thorough overview, see https://cpsievert.github.io/plotly_book/key-frame-animations.htmlframe argument to plot_ly() for creating animations. Also added the animation_opts(), animation_slider(), and animation_button() functions for configuring animation defaults.plotly_POST() and get_figure() functions obsolete (use api_create() and api_download_plot() instead), and thus, are now deprecated, but remain around for backwards-compatibility. For more details, see help(api).ggplotly(): GeomCol, GeomRug, GeomCrossbar, GeomQuantile, GeomSpoke, GeomDotplot, GeomRasterAnn (i.e., annotation_raster()), and GeomAnnotationMap (i.e., annotation_map()).raster2uri() which makes it easier to embed raster objects as images via data URIs. For examples, see help(raster2uri).ggplotly() gains a new argument, dynamicTicks, which allows axis ticks to update upon zoom/pan interactions (fixes #485).plot_dendro() function for a quick and dirty interactive dendrogram with support for hierarchial selection. For more, see – https://plotly-r.com/client-side-linking.html#fig:dendroexport() function gains a selenium argument for rendering/exporting WebGL plots and exporting to ‘svg’/‘webp’ file formats (via the plotly.js function Plotly.downloadImage()).legendgroup (see #675, #817, #826).plotlyOutput() function gains a inline argument which makes it easier to place multiple plots in the same row (in a shiny application).ggplotly() now applies format() to automatically generated hoverinfo. This will allow for finer control over the text displayed (for instance, options(digits = 4) can now be used to choose the number of significant digits used). See #834 for an example.HTMLwidgets.renderValue() should now avoid creating too many active WebGL contexts (thanks @AleksandrIanevski).remove_typedarray_polyfill() was added to make it easy to remove it. Fixes #824, #717, #825.ggplotly() now tries to open/close a Cairo graphics device, then a bitmap (png/jpeg) device. If neither is available, it errors. This helps to ensure that a screen device is never opened by ggplotly() (which fixes #829). Furthermore, if width/height is not specified and no graphics device is currently open, a default of 640/480 is used for width/height of the device.geom_bar(), geom_histogram(), geom_col()). Fixes #560, #874, #901, #831.geom_bar() via ggplotly(). Fixes #557 and #662.embed_notebook() now works in nteract notebooks (see #768).ggplotly()). Fixes #804.ggplotly()). Fixes #861.timezone argument in ggplot2’s scale_datetime(). Fixes (#743, thanks @earowang).p, do config(p, modeBarButtonsToRemove = "Collaborate")layout() is now deprecated. Specify in ggplotly() or plot_ly().ggplotly() function now preserves all information about the layer mapping. This makes it possible to access input/output data from any layer.layout.width/layout.height.height/width are specified in ggplotly(), relative sizes are now translated correctly. Fixes #489 and #510.ggplotly() on a plot with geom_line and group aesthetic wrong tooltip information was shown. Fixes #774.colors argument.colorbar() function gains a new limits arguments for controlling the colorscale limits.z is now required in add_heatmap(). If you want a z to be computed, use add_histogram().split, replaces the old functionality of the now deprecated group argument by creating one trace per value.subplot() without a specified color (once again) match the coloring defaults supplied by plotly.js (see #724).subplot()colorbar() function now works on colorbars generated via z mapping.plot_mapbox() and plot_geo() functions, which make it easier to work with the “scattermapbox”, “scattergeo”, and “choropleth” trace types. See the maps chapter of the plotly book for some examples – https://cpsievert.github.io/plotly_book/maps.htmlsubplot() now accepts, and correctly scales mapbox objects.add_mesh3d() and add_pie() functions as wrappers around the “mesh3d”, and “pie” trace types.add_scattergeo() and add_choropleth() functions have been deprecated in favor of plot_geo().add_area(...) function changed it’s meaning from add_lines(..., fill = 'tozeroy') to a wrapper around the area trace https://plot.ly/r/reference/#area. This is more consistent with the naming conventions already in place for other add_() functions.add_ribbons() now shows points (instead of fill) on hover.rangeslider() function to make it easier to add a range slider to the x-axis.colorbar() function to make it easier to modify an automatically generated colorbar.plot_ly(mpg, x = ~cty, y = ~hwy, symbol = ~factor(cyl), color = ~factor(cyl)))inherit argument for all add_() functions to avoid inheriting attributes from plot_ly().add_fun() function to add layers to a plot without modifying the original data associated with a plotly object.add_annotations() function to make it easier to add annotations.layerData argument to ggplotly() to make it possible to retrieve the data from a particular ggplot2 layer.marker.line.color is now transparent by default.marker.colorbar.add_choropleth() previously wasn’t relaying the z attribute.add_segments() (resulting in incorrect axis category order).plot_ly() when the number of traces is a multiple of ten.event_data() now works inside shiny modules (#659). For an example, see https://github.com/ropensci/plotly/tree/master/inst/examples/shiny/event_data_modulesadd_bars().as_widget() function was exported to make it easier to convert a list (adhering to the plotly spec) to a plotly htmlwidget object. This should only be needed when “manually” editing the underlying list object.plotlyOutput(). In order to make this possible, ggplotly() now has a method for plotly objects (the identity function), and ggplotly() called on any expression provided to plotlyOutput().geom_text().last_plot() can now be used to retrieve the most recently printed plotly graph. Thanks to this new feature, when plotly_POST() is called with no plotly object supplied, the most recently printed plotly graph is sent to the users plotly account.colors/symbols/linetypes arguments now accept named character vectors. The names specify the domain (i.e., data values) and the values specify the range (i.e., visual encodings). This is mainly useful to ensure a particular (discrete) data value is mapped to a particular visual attribute (yes, this is similar, in spirit, to ggplot2’s scale_*_manual()).scales::shape_pal() and scales::linetype_pal().color/symbol/linetype, domain values are sorted alphabetically before scales are applied. Also, when mapping a factor to color/symbol/linetype, domain values are sorted according to their factor levels before scales are applied. This leads to more consistent (categorical axis ordering behaves similarly) and predictable (compared to having values sorted in the order in which they appear) behavior.alpha is now applied when color isn’t specified (fixes #658).plot_ly() now orders the categories of a discrete x/y axis according the level ordering (if a factor) or alphabetical order (if a character string). Fixes #578.ggplotly() gains a new originalData argument which allows one to attach either the original (global) data, or a “scaled”/“trained” version of the data used by ggplot2 to draw the graph (for a quick example, ggplotly(qplot(1:10), originalData = FALSE) %>% plotly_data()).geom_polygon()/geom_hex()/geom_rect()/geom_map()).stat_identity() is used, group domain values are preserved and displayed in hoverinfo.hide_guides()/hide_legend() were added (these work similarly to the existing hide_colorbar()) to simply the hiding of guides (i.e., legends/colorbars).facet_wrap() should now be correct.plot_ly(mtcars, x = wt, y = mpg, color = vs) should now be plot_ly(mtcars, x = ~wt, y = ~mpg, color = ~vs). This is a major breaking change, but it is necessary to ensure that evaluation is correct in all contexts (as a result, evaluate argument is now deprecated as it is no longer needed). It also has the benefit of being easier to program with (i.e., writing your own custom functions that wrap plot_ly()) since it preserves referential transparency. For more details, see the lazyeval vignetteas.widget() function has deprecated, and serialization/memory leak problems are no longer an issue. This change also implies that arbitrary data manipulation functions can no longer be intermingled inside a plot pipeline, but plotly methods for dplyr’s data manipulation verbs are now provided (see ?plotly_data for examples).group variable mapping no longer create multiple traces, but instead defines “gaps” within a trace (fixes #418, #381, #577). Groupings should be declared via the new group_by() function (see help(plotly_data) for examples) instead of the group argument (which is now deprecated).plot_ly() now initializes a plotly object (i.e., won’t add a scatter trace by default), meaning that something like plot_ly(x = 1:10, y = 1:10) %>% add_trace(y = 10:1) creates one trace, instead of two. That being said, if you manually specify a trace type in plot_ly(), it will add a layer with that trace type (e.g. plot_ly(x = 1:10, y = 1:10, type = "scatter") %>% add_trace(y = 10:1) draws two scatter traces). If no trace type is provided, a sensible type is inferred from the supplied data, and automatically added (i.e., plot_ly(x = rnorm(100)) now creates a histogram).inherit argument is deprecated. Any arguments/attributes specified in plot_ly() will automatically be passed along to additional traces added via add_trace() (or any of it’s add_*() siblings).color, symbol, size) is applied at the plot-level, instead of the trace level.linetype/linetypes arguments for mapping discrete variables to line types (works very much like the symbol/symbols).I() (closes #428). This is mainly useful for changing default appearance (e.g. plot_ly(x = 1:10, y = 1:10, color = I("red"))).pch and lty values (e.g. plot_ly(x = 1:25, y = 1:25, symbol = I(0:24)))alpha argument controls the alpha transparency of color (e.g. plot_ly(x = 1:10, y = 1:10, color = I("red"), alpha = 0.1)).sizes argument for controlling the range of marker size scaling.add_polygons()/add_ribbons()/add_area()/add_segments()/add_lines()/add_markers()/add_paths()/add_text() functions provide a shorthand for common special cases of add_trace().toWebGL() function for easy conversion from SVG to WebGL.export() function makes it easy to save plots as png/jpeg/pdf (fixes #311).plotly_data() function for returning/inspecting data frame(s) associated with a plotly object.plotly_json() function for inspecting the data sent to plotly.js (as an R list or JSON).layout() is now a generic function and uses method dispatch to avoid conflicts with graphics::layout() (fixes #464).3.6.5 – 10 June 2016

NEW FEATURES
New event_data() function provides easy access to plotly events in shiny. For an example, see https://github.com/ropensci/plotly/tree/master/inst/examples/plotlyEvents
plot_ly() and ggplotly() gain a source argument to differentiate between plotly events in shiny apps with multiple plots. ggplotly() also gains width and height arguments.
CHANGES
The arguments filename, fileopt, world_readable in ggplotly() were removed as they should be provided to plotly_POST() instead.
