R is used *as such* in corporate environments all over the world
and
1) it comes with a GUI (on Windows and Mac),
2) comes with extensive documentation and
3) has facilities for HPC using add-on packages most
of which are listed here:
http://cran.r-project.org/web/views/HighPerformanceComputing.html
That being said there is a diversity of companies
providing commercial services related to R and
innumerous initiatives focusing on particular aspects
which might be useful to "corporate" contexts as well.
Best,
Tobias
P.S. This is IMO not a subject to be discussed on R-devel.
