[R] R or Splus?

It's been suggested I use R, I suppose because my employer is too skint to pay
for a copy of Splus.
But.... it doesn't seem to be stable. I was trying to do some ordinary regression
and stepping through a model. I was trying to set up a model ('kitchen_sink') in
which to put all my model parameters. Then I wanted to use step() to see what it
would reduce the model to. I couldn't even get started though. I would specify
the same model again and again, with just a few of the possible variables, and
sometimes lm() would fall over and return an error message, sometimes the regression
ran fine. I got fed up and ftp'd the original tables up to a machine running
Splus, where the models ran fine, every time, with all kinds of specifications.
Is this a normal experience? Is R buggy or what? I note the other email that
R can't handle files named x. If I can use Splus, should I just do that?
(Alternative is graphics-interface-only SPSS, and given that I've never used it,
I'm working on remote machines, from home, with no manuals handy, that is something I
should really wish to avoid :-).
