[STATSGRASS] [newbie] can't use rast.put

[Lionel]

I found the reason of my problem

> R >rast.put(G, "test", test, "Test",cat=FALSE)
> Error in rast.put(G, "test", test, "Test", cat = FALSE) :
>         layer is neither numeric nor factor
R >rast.put(G, "test", test$dem, "Test",cat=FALSE)
works better.

thanks
