Inefficiency of SAS Programming

I whole heartedly agree with Frank here. It may be one thing to have a
"translation" process in place based upon some form of logical mapping
between the two languages (as Bob's book provides). But is another thing
entirely to actually start writing functions that provide wrappers
modeled on SAS based PROCs.

If you do this, then you only serve to obfuscate the fundamental
philosophical and functional differences between the two languages and
doom a new useR to missing all of R's benefits. They will continue to
try to figure out how to use R based upon their "SAS intuition" rather
than developing a new set of coding and even statistical paradigms.

Having been through the SAS to S/R transition myself, having used SAS
for much of the 90's and now having used R for over 7 years, I can speak
from personal experience and state that the only way to achieve the
requisite proficiency with R is immersion therapy.
