Wow!
Jim, this really  *IS* good news!

Just a moment ago, I had a phone call from an applied person here in CH who
uses R (for windoze, at his home), and asked how to do ANOVA problems with R.  

He was also badly missing S-plus's  aov(.) function...
and I explained how he could  use   anova( lm(...) ) for FIXED effects
anova, and that nothing is yet available for random (or mixed) effects.

Martin.
