Hi all,

    I am not sure this is a bug rather than an intentional design, but here
goes:
If I do

> a <- matrix(1:4, nrow=2)
> dimnames(a)[[1]] <- c("a", "b")

I get the following error message because dimnames(a) is NULL:

Error: more elements supplied than there are to replace

What is the proper way to do this?  I know this works:

> dimnames(a) <- list(c("a", "b"), NULL)

   Incidentally, in SPlus, I can assign to NULL dimnames.

Thanks,
Hsiu-Khuern.
