Hello together,
I was wondering how I can solve the following conversion problem of a
raster file: when I try to convert the values from the raster (r) from
numeric into a factor via as.factor(r) always the error appears: "Error
in 1:ncol(r) : argument of length 0".
r <- raster(ncol=5, nrow=5)
values(r) <- 1:ncell(r)
as.factor(r)
Urgently I have to figure out how to convert a numeric raster into a
factor raster for a predict() calculation within the raster package.
Every hint is very welcome!
Best,
Stefan
