I'm looking at RInside and RCpp. Someone in one of my grad school classes mentioned something about a COM object interface to R. Really, I don't care how it gets done, but I need to prototype something quick. Suggestions please? One problem is that I have to get the thing to work in Windows. As an example, suppose in C++ I wanted to use the lm() function and then extract the t-value associated with the hypothesis test of whether Beta is 0; I'd like to extract that Beta value out of R from code in C++.
