[R-sig-finance] RE: R vs. S-PLUS

[Daltonmota at aol.com]

I have used both, and they very close to each other, being the main difference the already stated commercial support.

My personal preference is for R, since i belive the open architeture offers much more contribution possibilities among user community. 

For the very very risk activities where i cannot commit any error, i also use mat lab software, in place of R, or to check the main results outputed by R.

summary of my opinion :
Academic or personal use : R
Usual Professional activity : R
Very Risky or very complex Professional activity : R and/or S-Plus/Mat Lab to validate
