If you are running a script by R CMD BATCH (or otherwise by redirectin)
there is no limit on the number of lines (apart from file sizes on your
OS) and I have used several tens of thousands of lines with auto-generated
scripts.
There is a limit on the length of command lines, I believe 1024 chars on
all implementations of R.
