R is a free version of S-Plus. If you program in R then you use the
program in S-Plus it works ... usually.
Imho S-Plus is a great statistical package and one of its strength is
the graphical part. The difference is that s-Plus is more near to SPSS
as interface, R to SAS. You can found a lot of specifical techinchs
developed by someone and put at disposition on internet.
Learning R is not too difficult, but it's better to use directely on a
project and learning on the field
The strength of R is being free. I don't know, but I would, if is
comparable to SAS for managing big data set
