Such as? Are these features so important for you work that you need s-plus?

You can also get technical support for R, REvolution Computing for example.

If I learn to do something using a package in R, is their some way to bring that into S-Plus? I've noticed that some R packages, such as MASS and Hmisc are in S-Plus but are unsupported. Others, such as reshape, appear not to be in the program but I thought maybe they could be imported.

I would say, if it is not necessary, use one product and not two. 
Problems like the one below can be avoided in that case.

cheers and good luck,
Paul

Yesterday, I ran some code from the MASS package in S-Plus but the program didn't produce the graph I exepected to see. I've been able to use windows() in R to correct this, but S-Plus doesn't recognize that. So I was wondering how often code written in one program would fail to work in the other.
