Suppose you have got used to Splus and want to switch to R software (why bother to change? R is free while Splus is not, fair enough?), what can you do? since there are many functions in S-PLUS that are missing in R, one way is to understand the functions and write your owns, working N hours without sleep (N>?). however, you can avoid doing like that if you are as headche as me whenever you think of this solution. There is a package named Splus2R, which is to facilitate the conversion of S-PLUS packages to R packages, this package provides some missing S-PLUS functionality in R.
I have not tested the package, though, will update later. Here is downloading link: http://cran.r-project.org/web/packages/splus2R/index.html.
