News

version 0.3-1

• handle bounds, when given, in read_ncdf

• provide time parsing (POSIXct, PCICt) for read_ncdf; #115

version 0.3-0

• 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

version 0.2-0

• 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

version 0.1-1

• add meta data reader to read_stars

version 0.1-0

• 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

version 0.0

• interface the 9 C++ gdal utils through gdal_utils() (now part of sf)
