I use to say that 97% of S(plus) user written code works unaltered in R. The problem is with the remaining ones. The R FAQ (mentioned in the footer of every R-help message) contains a section on intentional differences between R and S(plus). You might want to work with just one version of code and use the if(is.R()) { ## R } else { ## Splus } The function is.R (in R) is written such that it should work in all versions of S.

If not, check the R-FAQ for differences to S-Plus. In my experience, they're not big. There are some areas where S-Plus offers more features (for example, R does not include Trellis graphics). If you're using something from an external library, remember to load it in R first (with "library(something"). That got me a few times. If it still doesn't work and you're really interested in finding out, look up "S Programming" by Venables and Ripley (Springer, 2000) which covers the fundamental differences between both implementations in-depth; or come back to the list with the problems.
