[R] Are you experienced in SAS ...

I'd just like to put in my two bob's worth:
The ***only*** thing for which I prefer SAS to R/Splus, but it's
a very important thing, is the analysis of mixed linear models.
One can do the same analyses in both languages. The difference is
that the SAS syntax for specifying such a model, and its output, is
comprehensible to the human mind, which is what I'm equipped with.
The R/Splus syntax (which involves the bewildering notion of
``strata'') is not.
Actually, for this sort of problem, I prefer Minitab to SAS.
It has the same sytax as SAS, and is much more user-friendly.
Aside from that, R/Splus wins. I find data manipulation far
***easier*** in R than in SAS. SAS had ***one*** data structure:
The data frame. You are hand-cuffed into it, and all manipulations
must be contorted to fit this structure. In R/Splus, the sky's
the limit. The flexibility of R/Splus puts the user in control,
and if the syntax gets unweildy, you can roll your own function
to turn a complex command into a single word.
It bears repeating that for mega-line data frames apparently SAS
can do easily things that bring R to its knees. I have no personal
experience in this regard, but.
