With terra_1.5-19, raster_3.5-15 that reprex works for me:

You are right. Sorry, I checked it with an outdated version of terra.
Hello. Thank you for the excellent package.
I recently have been converting raster code to use terra and noticed some issues / changes in
terra::levels()
v.s.terra::cats()
.levels()
is a list of vectors containing the levels (no column names/ID), whereascats()
has (list of) ID, labels, colors, and other categories in data.frames (the RAT).Fixes
Error in x@ptr$replaceValues(from, to, -1, opt): Not compatible with requested type: [type=NULL; target=double].
