[R] SAS VS R - What type of analysis is better?

I can't think of an example where R does not work better than SAS except 
for a few cases of mixed effects regression models and for processing 
enormous datasets when the R user does not want to learn about the 
latest R tools for large datasets.  I quit using SAS in 1991 (in favor 
of S-Plus and transitioned to R around 2000) and have never looked back. 
  Lately what has really made R powerful is its ability to interface 
with other languages and especially the way it works in a reproducible 
analysis/dynamic report document context.
