Splits a categorical raster layer (or a vector) into a multilayer raster (or matrix).
oneHotEncode(img, classes, background = 0, foreground = 1, na.rm = FALSE, ...)
A SpatRaster with as many layers as there are classes. Pixels matching the class of interest are set to 1, backround values by default are set to 0 (see background argument)
RasterLayer or SpatRaster or integer/numeric vector containing multiple classes
integer: vector of classes which should be extracted
integer: background value (default = 0)
integer: foreground value (default = 1)
logical: if TRUE
, NA
s will be coerced to the background
value.
further arguments passed to writeRaster. Ignored if img is not a SpatRaster, but a numeric/integer vector or matrix
