fix bug in st_as_stars.Raster
add s2
to Suggests:
st_rgb
collapses (reduces) a dimension to rgb hex value; #302
aggregate.stars handles arrays with NA values now correctly; brought up in #299 by Thorsten Simon
aggregate.stars
gains an argument exact
which, if TRUE
, calls exactextractr
for polygonal aggregation; #289
read_stars
reads all subdatasets with dimensions equal to first, and warns when ignoring others; #296
make copying over of dimensions somewhat easier; #295
st_as_stars.Raster
tries to read from file if the raster object is not an in-memory object.
write_stars
normalizes path, as read_stars
already did; #293
merge
for proxy objects acts, and is no longer lazy; #290
st_as_stars.Raster
returns a proxy object if the raster layer is on disk
add st_extract
to extract e.g. time series from grids at point locations; #279; #290
read_stars
chooses a value for proxy
that depends on the data dimensions; #281
x/y range subsetting of stars_proxy
objects now only reads that range, similar to how crop already did this.
st_warp
preserves levels and colors; https://github.com/mtennekes/tmap/issues/429
st_crop
works with bounding boxes larger than the downsampled bounding box; #276
st_crop
has a non-zero default for epsilon
(bounding box shrinkage) to exclude cells touching the crop bounding box; #275
image.stars
(and hence plot.stars
) gains an extent
argument for setting the extent of a plot; https://github.com/r-spatial/sf/issues/1193
st_warp
(stars native) flips longitudes a full cycle; #256, #264, #269
handle axis order in st_transform
(requires sf >= 0.9-1)
depend on sf 0.9-0
adapt to cubelyr split-off from dplyr; add cubelyr to Suggests:; https://github.com/hadley/cubelyr/issues/2
add droplevels
method
handle color tables, category tables and raster attribute tables read through GDAL; #128, #245; https://github.com/r-spatial/mapview/issues/208
handle dimension crs
specially, for proxy objects now.
handle new-style crs
objects from upcoming sf, moving away from proj4strings
handle full crs
objects as refsys
element in a spatial dimensions, rather than proj4string only
st_raster_type(x)
reveals the raster type of x
; #248, https://github.com/mtennekes/tmap/issues/368
add st_as_stars.OpenStreetMap
method; #241 by @mtennekes
add st_flip
to flip arrays along one or more dimensions without changing dimension properties
add as.owin
method to convert (2D raster) stars objects to spatstat owin
; https://github.com/r-spatial/sf/issues/1233
for temporal aggregation, aggregate.stars
now also takes by
arguments like “week”, “month”, or “5 days”
add st_as_stars
method for xts
objects; improve as.xts
for stars
objects
skip some tests on solaris
plot
now uses all data to figure out breaks, in order to also find extremes; #216
st_mosaic
creates mosaics from spatially disjoint rasters; #210
#205 large refactoring of read_ncdf
, by David Blodgett and Mike Sumner, affecting #199, #89, #30, #86, #175
allow for funny units like m s**-1
; #201
add contour
method for stars
objects; #196
plot uses rasterImage
by default if available; #194
the x
and y
raster dimensions can be set and unset with xy
argument in st_set_dimensions
; #190
retain factor
levels with dimension values when set in st_set_dimensions
; #188
add conversion from stars_proxy
to Raster
: #193
make plotting of multiple curvilinear grids work
plot by default no cell borders in case of curvilinear, rotated or sheared grids
robustify handling of units
allow read_ncdf
to ignore bounds
scale was applied wrongly on multi-band images; #189, this requires sf >= 0.7-5
.nc
is now recognized correctly by write_stars
and will write a NetCDF file; #186
[
subset now works correctly with negative or logical indices; #184, #185
NA
values for float32 grids are now correctly detected; #182, this requires sf >= 0.7-5
cropping of a stars_proxy
object now works; #179
st_apply
can now loop over Raster layers; examples in #176
st_as_stars.bbox
now has an ncells
and pretty
argument, to better choose default raster dimensions
geom_stars
now works with stars_proxy
objects, but needs downsample
to be set; #21
NA
values in Float32 rasters are now read correctly with read_stars
; #182
handle bounds, when given, in read_ncdf
provide time parsing (POSIXct, PCICt) for read_ncdf
; #115
add st_area
method to return raster grid cell sizes; #99
fix st_warp
with use_gdal=TRUE
, allowing for multi-band warps
add st_get_dimension_values
to get the values of a particular dimension (if meaningful); #100
allow for setting intervals as dimension values; see examples of st_dimensions
add st_contour
, and clean up st_as_sf
; #99
experimental color table support; https://github.com/r-spatial/mapview/issues/208
rewrote vignettes, added vignettes; #99
deprecate st_write.stars
for write_stars
; #96
use “native” R array-factor support
support for PCICt
360- and 365-day calendars; #29
remove import of ncdf4
in favour of RNetCDF
, now in line with practice in ncmeta
package. Thanks to David Blodgett for motivation and testing (see #87, #94).
st_as_sf
uses date/time column names when appropriate
allow missing trailing comma’s when subsetting: a[1,,]
and a[1,]
now do the same.
move rlang
to Imports: ; rewrite [
subset using rlang.
add conversion to and from Spatial*
classes, including the gridded ones, taking care of factor
variables
depend on sf 0.7-2
add logz support for log-scale keys to plot
and image
vignettes now use an external package, starsdata
, for larger dataset examples
support [<-.stars
e.g. to mask out values; support is.na.stars
to replace NA masks
support cut
methods and factor arrays (plot, subset); #56
add st_rasterize
, which uses GDALRasterize
to rasterize an sf object; #13
st_as_sf.stars
now uses GDAL(F)Polygonize
when give a regular or sheared grid grid cells are not points, and returns contour bands using GDALContourGenerateEx
(requiring GDAL 2.4.0) in case cells are points; #13
support curvilinear grids; see #54 and the data_model
vignette
add vignette about how stars_proxy
objects work
stars_proxy
objects defer processing of st_apply
jobs until after subsampling; #50
allow reading sections of a raster, raster at a lower resolution, selected bands; #48
allow reading vectors (arrays) with more than 2^31 elements; #48
fold all higher dimensions into the third dimension before coercing to Raster
; #40
read_stars
add merge
(merge attributes into array dimension) and split
(split dimension over attributes)
interface to sf, raster and spacetime
improve plotting
handle logical
arrays in plot
add st_apply
, analogous to apply
add cropping/masking when used as x[buf] with buf an sf
, sfc
or bbox
object; masking when x[buf, crop = FALSE]
add Ops (+,-,/ etc) and Math (sqrt, pow, sin etc) methods
add dimnames
and dimnames<-
methods for stars objects
downsample large grids to only plot pixels actually shown
can plot rectilinear grids (but will plot rgb images as regular grids)
rgb
argument to image
works
[
array-like subsetting works; first index is attribute selector
gdal_utils()
(now part of sf
)
