Hey All,

I was wondering if I could solicit a little input on what I'm trying to do here. I have a list of matrices, and I want to set their dimnames, but all I can come up with is this:

x <- matrix(1:4,2)
y <- matrix(5:8,2)

z <- list(x,y)
nm <- c("a","b")
nms <- list(nm,nm)

z <- lapply(z,function(x)dimnames(x)<-nms)

As you can see, this doesn't quite work. Could anybody help me, and bonus points if you can help me do this efficiently. Please cc my email address, because I only get summaries of the list.

Thanks in advance!
