[R] Boxplots illustrating the fixed effects in a lme object

As with many things, I suspect that someone has created plots of this  
sort, but no-one seems to have contributed a function to do so.  If  
you find/create one, send it to me and I'll be glad to include it in  
either gmodes or gplots as appropriate.

One place to check before writing one is Frank Harrell's Hmisc or  
design packages, which do have functions for plotting estimates and  
standard errors for (at least) standard glm's.  These might work for  
lme's as well...
