R help - Dec 2011 - Writing out in loops

I would like to write some data to different files. I can create the  
filename Day1.txt like this:

filen <- paste("Day", l, ".txt", sep="")

and then I'm using a For loop to write out one row of a matrix,  
something like this:

For (j in 1:10)
{
cat(mat[1,j], ",", file=filen, append=TRUE)
}
cat("\n", file=filen, append=TRUE)

but is there a better way to do this?

Thank you,

Thomas

Is there some reason you can't create the entire file in R and then write it
out in a single step?

It looks like you're writing out
mat[1, 1:10]
so you could just use
write.table(mat[1, 1:10], filen)

Can you expand on what you're trying to do?
