OK, dumb question, and it is probably in the docs somewhere, but after
12 months working with R and quite a while looking at the docs, I still
don't know (or have forgotten) how to replace all NA values in a matrix
at once with some other value. I can do it column by column using
is.na(), but I can't figure out how to do it for the whole matrix. My
apologies, I am ashamed ;-)
