Not exactly.

If you wish to keep ***inadvertant*** changes from being made, you could 
put bundle everything in an R package, protect the core computations in 
functions that are protected in the package namespace so the user can only 
see wrapper functions, and provide a Windows binary. See Writing R 
Extensions for info on namespaces.

Your users will still have to have R.

A devoted hacker will hardly be slowed down by this, but curious noobies 
will be protected from themselves.

HTH,

Chuck
