Many people find S-plus to be easy to grasp and intuitive to an almost prescient degree. S-plus has allowed even the novice user to produce excellent graphics and to implement sophisticated algorithms in a straightfoward way. However, there is one defect that anyone who has written an S-plus for-loop knows, interpreted languages, like S-plus, are slow. Moreover, due to the memory management techniques employed by S-plus, it is easy to unintentionally eat up the available memory resources in unused but nevertheless allocated data frames.

The S-plus compiler, Scompile, was written to circumvent the aforementioned problems. Scompile translates a given S-plus program file into C, which then gets compiled by your local C-compiler. The compiled code is then loaded into the current S-plus session using the dynamic loading mechanism. Subsequent calls to the function(s) defined in the original S-plus program file will run the compiled C version. These are pretty much the same steps one would take if they wanted to recode a S-plus function into C, except the whole process (including writing the C) has been automated.
