R help - May 2011 - Is this confict of different versions of R or something else?

Hello!

I have had some problems lately with use of R at home and school. At my home
laptop (Ubuntu linux 64bit & R-2.12.0) R works just fine. But when I take my
codes to school(Windows XP 32bit & R-2.10.1 I think) and run those there
those codes probably won't work. Functions as combinations() didn't work
and
expand.grid() worked a bit differently. About expand.grid I just couldn't
pass a dataframe of parametres but I had to pass all the colums separately.

Is this because my university has so old version of R? Or is it because I am
using Linux at home? Or is it because some libraries aren't installed?
I like R very much, but if there is difference between R in different
operating systems, then I dislike that.

Can you give me some tips how to avoid these problems? Install latest R to
my university PC? I don't want to fall back at Windows users -category
anymore.

Hm. Untill now I thought that different versions are for introducing new 
features, properties or enhanced computing. You can not expect that 
everything what works in new version will work in any older version.

There can be slight issues with different operation systems, however I 
believe the biggest problem is old R version in your school PC.

No documentation for 'combinations' in specified packages and libraries:
you could try '??combinations'

So I (like you) don't have the package with combinations loaded.

That is most probably a version difference. The Core group works very  
diligently to keep the versions returning the same results (when  
possible) on all platforms. Graphics and operating system-specific  
tasks (including clipboard access) are obvious
exceptions.
