Hi Jason,
Duncan Temple Lang answered a similar question for me last year and wrote
up the method here: http://dsi.ucdavis.edu/Notes/R/FindingNativeCodeInR.html
Basically the C level debugger can be very helpful for figuring out what's
happening.
Best,
Clark

Chuck and Greg,
Thanks a lot for your help! I have a much better understanding now of what is
happening “under the hood”.
Kind Regards,
Jason

(executed from the root of an R source tree), is your friend.
cheers, Greg

it is called. I finally managed to track down the C course at:
