I use (and like) both R and Splus. In my case, it has nothing to do
with how much they cost: I know that my employer is more interested in
my productivity than in the cost (within reason, of course) of my data

This is *not* at all my experience with R. Typically, I use some development
(i.e.,"unstable") version of R, yet it rarely gives me any trouble. (BTW
I'm puzzled by your impression that R can't handle files named x -- obviously
a misunderstanding by someone.)

Both R and Splus have good online documentation (help pages and PDF version
of their user/programmer guides). Again, this shouldn't be an issue.
I'd suggest to take a closer look and decide for yourself
based on your needs and the functionality they provide; if it costs
money, well that's one of the tools you need to get your job done
(together with your desk, computer, telephone, fax, ....).
