loon 1.3.1

• Added new functions l_loonWidgets() which returns widgets of all displayed loon plots. Related functions include

  • l_basePaths() and l_compoundPaths
  • l_getFromPath()

• Fixed bug so that l_make_glyphs() again works in Mac OS Catalina (Thanks to Brian Ripley and Simon Urbanek)

  • Cool new example there which produces the Periodic Table of the Elements as a scatterplot (data “elements” from loon.data package).
    Actually see the periodicity by brushing.

• A minor bug fix with respect to facet label layout

• “color”, “size”, “linewidth”, “glyph”, added to ‘l_userOptions()’

  • default “color”, “size”, “linewidth”, “glyph”, etc. now set to look up default ‘l_getOption(“linewidth”)’ etc.
  • this allows the user to change the default look of all plots simply by using ‘l_setOption(“color”, “black”)’ for example.

loon 1.3.0

• several new features added to loon plots
  • NAs are now accommodated
  • histograms recognize factors to produce barplots
• group by and facetting in loon plots
  • l_plot() and l_hist() now accept arguments by and facet
• improved docuentation
  • new vignettes
  • better organized reference manual via l_web()
• in some OSes the function l_image_import_files() has stopped working
  • seems to be a problem with the tcltk function tkimage.create()
  • tkimage.create() function works on older .png files but seemingly not on newer ones
  • l_make_glyphs() calls l_image_import_files() and so although it will still create the necessary png files, it may fail to read them back in.
  • the problem has been observed (unreliably) to work if the png is further processed outside R.
  • so demo(“l_make_glyphs”) has been removed

loon 1.2.3.9000

• deprecated l_saveStatesRDS()
  • replaced by l_saveStates
  • reasoning for name change is to have the same name be used in the Python release for the same functionality
  • introduced l_getSavedStates() to read the states (instead of readRDS for the same reason as above).
• updated l_cget()
  • Fixed reading of labels to retrieve raw characters so that braces etc. can appear in labels
  • updated l_hist.factor so that a layer of factor level labels appear below the corresponding bar

loon 1.2.3

• added l_saveStatesRDS()
  • saves named or all states to disk for later retrieval (e.g. in Rmarkdown)
• added l_copyStates(source, target)
  • copies the info_state values of source to that of target.
  • some basic states are excluded but can be overridden.

loon 1.2.2

• added l_plot3D contributed by Martin Gauch (for rwo)
• l_pairs linking issues and arguments for histograms and serialaxes in the display are fixed
• added a new vignette “loon and RMarkdown” and tidied up some others
• new functionality to make it easy to construct statistical glyphs from any R plotting function
  • new demo(l_make_glyphs) to illustrate statistical glyphs
  • tiny new data set oliveLocations for lat and long of olive data growing areas (used in demo)
  • tidied up a couple of demos (very superficially)

loon 1.2.1

• updated loonGrob() and grid.loon()
  • provide more meaningful grobs (including better descriptions and more informative “empty” grobs).
    
  • added condGrob() to effect the conditional construction of either the desired grob (if it is visible in the loon plot) or the empty grob as placeholder containing relevant arguments
• introduced the method plot.loon() so that plot(p) of a loon plot p will now draw the corresponding grid object on the current device

loon 1.2.0

• added loonGrob() and grid.loon() functionality

  • any loon plot can now be converted and saved as a grid graphics object
  • permits printing/exporting snapshots of loon plots in documentation
  • S3 class structure extended to more loon plots

• l_compound classes introduced to ease user creation of complex layouts

  • includes simple programming interface to extend loonGrob() to any user-defined
  • converted current compound layouts to new l_compound model (e.g. l_pairs, l_stl)
  • l_getPlots which returns a list of the loon plots in the display (works for simple loon plots too)
  • l_getLocations which returns a matrix showing the location of the loon plots (in order) (works for simple loon plots too)
  • l_get_arrangeGrobArgs which returns the arguments and their values to be passed on to arrangeGrob() (from gridExtra) to allow arbitrary layout by the user.
    • this is NOT implemented for simple loon plots (but could perhaps be)
  • loonGrob_layoutType which returns a string indicating whether "location" or "arrangeGrobArgs" are to be used when creating a grid version of the l_compound. (default is "locations", other possibility is "arrangeGrobArgs"

• Fixed widget handle class order: specific classes first.

• l_hexcolor.R

• l_plot_decomposed_ts

• l_cget and l_configure are now a generics with methods for objects of class loon, character, and l_compound.

• New functions l_getOption, l_getOptionNames, l_userOptions, l_userOptionDefault, l_setOption

• New function l_primitiveGlyphs

• names for loon object handles to print out the state names. l_state_names can be used alternatively

loon 1.1.0

• first release on CRAN
• change state names
  • itemlabel to itemLabel
  • showItemlabels to showItemLabels
• automatically convert nested lists and data.frames
  • unexported l_nestedTclList2Rlist and l_data
• remove the local copy of the website and make l_help point to the official website.

loon 1.0.1

• Bug fix in geodesic2d for 4d transitions

loon 0.9.1

• Bug fix when layering maps (sp classes) with asSingleLayer=TRUE
• Bug fix in scale_image

loon 0.9

• initial beta release for the general public
