[R & Unix ..] system("test",...) gives funny results...

One way to get an R internal "test"
       -- even working in the Win/Mac version of R ?! ---

...

However, this probably should have to be done by someone who understands
more than me about this kind of C codes.

I've often wondered about this too. In my "compatibility library" I do a few
similar things like copying files and checking file dates. I haven't implemented
them other than in Unix and I've often thought some cross-platform issues would
be resolved by doing these in C. Of course, this may just move the problem. To
what extent are these kinds of things standardized across platforms in C?
