R help - Jul 2009 - write matrix M including names(dimnames(M))

I can do this by writing (and reading) the file according to some format of
my own devising, but I'm wondering if there is a built-in way to write and
then restore a matrix with not only the dimnames (which
write.table/read.table can preserve) but also the names(dimnames)?

Example:
> M <- matrix(1:4, 2, 2)
> dimnames(M) <- list(xdim=c("a", "b"),
ydim=c("u", "v"))
> M
    ydim
xdim u v
   a 1 3
   b 2 4

There are two such matched combinations for saving R objects complete  
with attributes:

dput/dget  # will be more readable with a text editor than the next  
option

save/load  # not very readable
