Hello,
Does anyone have an example of calling into C level functions that would be
called with .Internal() in R?
Specifically, I'd like to call do_rank, as defined in:
http://svn.r-project.org/R/trunk/src/main/sort.c
These functions have an unusual signature, and I'm not sure what

Thank you to Romain and Dirk. I've seen some C++ rank implementations, and
I'll probably copy one of those.

Short version: Is it possible to instruct the code generator in
`compileAttributes` to source local header files when generating
RcppExports.cpp?
Long version: I'm trying to crib from the Dirk's examples in his recent UCB

Certainly. And while I ha

header (inst/include/RItools.h) the export function would auto-include was
exactly what I was looking for. This discussion also prompted me to think a
little more about the interface my package should export should anyone else
