You mean on a single line?
C code causes a hang-up, which can only be stopped with a quit signal that terminates the R session. Is this behavior normal?
No, works for me on Mac OS X and x86_64 Fedora 8 (as does 10x larger). Can you run this under a debugger and find where it is going wrong for you?
Code to reproduce this:
testChunk <- paste(rep("a", 10000 + 1), ## delete "+ 1" to be successful
collapse="")
output <- tempfile()
cat(testChunk, sep = "\n", file = output, append = TRUE)
We have writeLines() for that and it is more efficient, especially if you keep a connection open.
