I'm a newbie too, but I think it is just a "warning".
:) I suspect it is just to tell you that you are
appending to a file and not creating a new file. Iwas
a bit upset the first time I saw it until I realised
the write command was working just fine.

I suspect that you would have to join the two matrices
together in R.
cbind the two matrices xx <- cbind(mat1, mat2) and
then save the resulting larger matrix X . Will that
