[R] Too many open files

[Omar Lakkis]

This may be more of an OS question ...
I have this call

r = get.hist.quote(symbol, start= format(start, "%Y-%m-%d"), end=
format(end, "%Y-%m-%d"))
which does a url request

in a loop and my program runs out of file handlers after few hundred
rotations. The error message is:  'Too many open files'. Other than
increasing the file handlers assigned to my process, is there a way to
cleanly release and reuse these connections?

I run on Mac OS X
