...(Don't panic -- this won't happen quickly.) Mike writes f77 code. After some chasing about, I've realized that because optimization codes need to call the objective function written in R, they need to use a language that can do this. C can, Fortran cannot. There is, however, a package cfortran that allows for mixed coding in C and Fortran. This might not be the ultimate solution -- e.g., it may not be Windows usable. However, it could be a useful tool to try out some programs that are already available in Fortran. My query is to ask if anyone has experience they can share in using cfort...
