Richard: Assuming that you have installed R and are not trying to find everything on the website, you can list the code of any function by just typing the function name and <enter>
You will necessarily have to read the R code, but that is much easier than it may seem when you look at a couple pages of it, as you will when you list predict.lm Best wishes. Charles Annis, P.E.

I am not a programmer and studying the r code is extremely slow going. I have searched r-project.org and all the function help files without success. For example I have attempted to replicate by hand the se.fit calculation from a lm object calculated by a call to the predict function and have not been able to reproduce the results.
