fasterRaster 8.4.0.3 (2024-12-15)
Bug and issue fixes
o Many minor fixes for CRAN submission!

o fast() correctly defines region on import of raster.
o mow() example works.
o spatSample() works when sampling by stratum.
o .rbind() is a hidden function which accepts a cats argument that concatenates vectors faster than rbind().

Potentially code-breaking changes
o By default, fasterRaster now uses data.frames, not data.tables from the data.table package (see ?faster).
o Removed option clean from faster(). Files are now removed from the GRASS cache as needed.
o mow() can delete a single GRaster or GVector, a list of rasters and/or vectors, or all objects in a particular environment.
Enhanced functionality and new functions

Bug and issue fixes
o project() correctly restores the user’s “location” to that of the newly projected GRaster.
fasterRaster 8.4.0.7027 (2024-10-15)

o init() assigns to GRaster cells the value of their coordinates, rows, columns, or values in a regular or chessboard-like pattern.
o regress() replaces individual functions intercept(), slope(), r2(), and tvalue().
o subset() subsets layers of a GRaster or rows/geometries of a GVector.
o segregate() creates one layer per unique value in an input GRaster, with values in the output coded 1 or 0 depending on whether cells in the input had the unique value or not.
