A question, please about development of R packages: Are there any guidelines or best practices for deciding when and why to implement an operation in R, vs. implementing it in C? The "Writing R Extensions" recommends "working in interpreted R code . . . this is normally the best option." But we do write C-functions and access them in R - the question is, when/why is this justified, and when/why is it NOT justified?
While I have identified helpful documents on R coding standards, I have not seen notes/discussions on when/why to implement in R, vs. when to implement in C.
