[R] Functions similar to step() and all.effects() that work for lme() objects?

[Jon Zadra]

Hello,

I make frequent use of the *step()* and, for plotting, *all.effects() 
*functions for *lm()* objects.  I am now doing more with *lme()* random 
effects models, and haven't been able to find functions similar to 
*step()* or *all.effects()* which will accept *lme()* objects.  Do 
similar functions for either exist?  If someone could point me in the 
right direction it would be much appreciated.

Thanks!

Jon
