I apologize for what is likely a stupid question - I HAVE looked through
"Writing R Extensions" and HAVE gone through existing help requests, but
have not yet found an answer. I'm sorry if I've missed something obvious.

I am planning on building a package in the near future. I have a number of
C programs that I have written to interface with R (compiled using the R
SHLIB, run using the .C convention).

I now run a Linux system, but seem to remember that for Mac and Windows
implementations of R, Rtools is required separately in order to run
compiled C code that interfaces directly with R.

I am wondering whether any packages that I write using such C code will
require end users of PC and Mac to have Rtools installed, or whether there
is a way to build the package such that this is not the case.

I ask this because I would like the package to be relatively painlessly
portable, and know many users who have had trouble installing Rtools on
their Mac or PC.

Many thanks,
Adam
