Its not clear from your post which of the tests does not give you
the desired output and what the desired output is in that case.
Just guessing but maybe you meant to use testlist[[i]] instead of testlist[i] in
the loop?

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
