The general principle is that R packages are only allowed to use what is documented in the R help (? command) and in Writing R Extensions. The former covers what is allowed from R code in extensions, the latter mostly what is allowed from C code in extensions (with some references to Fortran).
Could you clarify what you mean by "documented"? For example, Rf_allocVector() is mentioned several times in R-exts, but I don't see anywhere where the inputs and output are precisely described (which is what I would consider to be documented). Is Rf_allocVector() part of the API? Hadley
