[R] Error with rgl loading in BATCH mode

[Prof Brian Ripley]

I don't think this is anything to do with BATCH mode: the machine you are 
running R BATCH on does not have GLU installed.  rgl *will* load on a 
system without an X server running.

KernSmooth does *not* require the rgl *package*, so you are (twice) 
blaming an innocent party.  You have doctored the output to give a false 
impression, and should be blaming some other package that loads all of 
KernSmooth, mvtnorm and rgl (perhaps package ks).

You truncated the output here without indication to give a misleading 
context.
