Hello,
This seems like a fairly elementary question, but I couldn't seem to
find the answer anywhere online.
Where can I find code which is called with .Internal? Specifically,
the R function colSums() calls an internal function with the same name
(I presume a C function), and I'd like to see how it works.
I've searched through the header files in R-2.x.x/include/ (Windows
version), but to no avail.
They are only used for external function to be able to link against R.
For .Internal() (for example), see ./src/main/names.c and the names they
refer to (also in other files in ./src/main)

Thanks,
