It's fairly informal, and mainly on the special functions level.
Gnumeric imports bits (all?) of R's standalone math library. You may
have seen some bug reports from terra at gnome.org (aka Morten Welinder)
on accuracy issues and the like. Morten is a Gnome/Gnumeric developer
and works with R-core members (I believe mostly Martin Maechler) from
time to time. If you look at Morten's reports, I'm sure you'll agree
that he is rather good at actively seeking out erroneous and
suboptimal code.
