Yes, you need to modify both the R and the underlying C code. It's the the source package on CRAN (the .tar.gz file).

However, it appears that the package was designed to only accommodate stratified sampling for classification purposes (see https://stat.ethz.ch/pipermail/r-help/2006-November/117477.html). As Andy suggests in the link just mentioned, I'm trying to modify the source code. However, it appears that I may also need to modify the C code that randomForest is calling, is that correct? If so, how do I access that code? Or, has anyone modified the package to allow for stratified sampling in regression problems? Please let me know if I'm not being clear enough with this question, and thanks for helping me out!
