It has been discussed internally, but as far as I remember no official document ever transpired. The general sentiment (still according to my memory) was that usage is OK as long as it doesn't imply endorsement by R Core or the R Foundation, or any other commingling with commercial products.

R and the "chocolate pretzel" logo are not registered as trademarks, but even if they were, then "nominative usage" (as described in the PSF Trademark Use Policy) should not be problematic. In cases of doubt, ask!
