[Rd] problem with Rcmdr Plugins

[John Fox]

Dear Erin,

I'm not sure why this is a problem with R 2.11.0 and not with earlier
versions (I'm sure that someone else will be able to answer), but it is
unnecessary for your plug-in package to require rgl, since rgl is already
loaded by the Rcmdr package at startup if it is present. The same is true of
tseries, abind, and MASS.

I hope this helps,
 John
