[R] Are you experienced in SAS and R as well? Which of these would you recommend?

Here at Purdue, the Statistics department requires that its students
learn both SAS and S/R. SAS is a necessary skill for work in industry,
since most employers use it, and since it handles large data sets well.
Unfortunately SAS is terribly awkward to actually DO anything with. I
used to program in FORTRAN IV, and the SAS data step reminds me of that,
only it seems a good deal worse.
A little over a year ago I had to work with a large data set from a
credit bureau. It was close to a gigabyte, and I found that SAS could
open the data and do things with it, even on a little laptop with only
144MB of ram. I used SAS to pick out several random samples of 10,000
observations, and worked on them with R. R is wonderfully flexible, and
I was able to do some exploratory stuff that I just wouldn't have
bothered to do with SAS. I also used R to do some ad hoc plotting which
suggested that my data followed a negative binomial distribution better
than a Poisson. Again, I could probably have done this in SAS, but I
certainly wouldn't have bothered.
I don't think that the choice between SAS and the dialects of S is an
``either this or that'' choice at all; you really should get familiar
with both, and use whichever is best for the job at hand.
Hope this helps you,
