Correct me if I'm wrong, but I think that write.csv() doesn't have an
append argument; write.table() does though.

What is the best way to write out comma separated data, as a program
is running (rather than waiting to the end using write.csv)? At the
moment I'm doing this, but I guess it's not the most efficient. The
data is in a column in the matrix postcount, and I'm using a loop to
write out each of the 100 elements.
for (j in 1:100)
{
cat(postcount[1,j], ",", file=filename, append=TRUE)
}
cat("\n", file=filename, append=TRUE)
Thank you!

Hi,
write.csv also supports an append argument. Maybe that is faster than
using cat.
cheers,
Paul
