SpatRaster objects do not seem to work as regular R objects, when it comes to being saved using save, or saveRDS, or serialize. Moreover no error or warning is produced when saving SpatRaster R objects. This means that this issue will cause data loss without warning when encountered.
The code below can be used to reproduce the issue.
> saveRDS(rast(nrows=108, ncols=21, xmin=0, xmax=10),'SpatRaster.RDS')
> r <- readRDS('./SpatRaster.RDS')
> r
class : SpatRaster
Error in x@ptr$nrow() : external pointer is not valid
Ideally, SpatRasters would behave like any other R object.
If the ideal solution is not preferred, alternatively serialize could be overloaded for class SpatRaster to give a clear error. Moreover, the documentation (?rast ?SpatRaster ?writeRaster) can be improved to warn users about SpatRasters limitation.
