Rscript, in all its wisdom, does not load the standard
methods
package. So precede your script withand all should be good.
If you're on Linux, you could use our littler package. It loads
methods
for you too, and starts a little faster than Rscript too.Edit It is now some five years later and this has been added to
Rscript
in R release 3.5.0 or later.
