[R] R routines vs. MATLAB/SPSS Routines

Many of these points are discussed in
a collaborative effort that I edited. In particular the final quote by
Jonathan Baron addresses point 5:
Another point, which I repeatedly make to students, is that R is
free and will continue to exist. Nothing can make it go away.
Once you learn it, you are no longer subject to price increases
(e.g., from zero, when, as a grad student, you use your advisor's
copy of SAS, to several hundred dollars or more after you leave).
You can take it with you wherever you go. The investment in
learning thus has a long-term payoff.
I don't agree with the characterization of appropriate fields for R.
R is rapidly gaining acceptance in finance. Demand seems to be
outstripping supply for people in finance with R skills.
