As for sharing analyses done in IML, couldn't folks post it on SASL as
well as SAS Community. That way it could have peer review.

This is definitely an issue. I've mentioned occasionally, but not on this
thread. You are at the mercy of the programmer.
OTOH, this is one reason that new statistical methods come out first in R.

R has no tech support.
I had S-Plus for a while, and it has good tech support.
The R-help list can be helpful, but it is not as friendly as SAS-Help,
certainly for newbies. OTOH, R-help has more statistical expertise than
SAS help does. There are a few people on SAS-L who *really* know statistics
at a deep level. On R-help, there are many. (This is different from being
able to be helpful..... I would *not* count myself as someone who *really*
knows statistics, but I do try to be helpful).

Yes, but 1) I see very few people *using* IML to do anything. and 2) When
they do, there is no mechanism for sharing.
