Hello,

I installed the newest version of R (3.0.2) as well as the 
newest version of
nlme (3.1-113) in order to use summary.lmList and other 
nlme functions. Once
loading the new library, lmList and summary.lm can be found,
 but a number of
additional functions cannot be found via command. 

Versions installed and loaded are correct. Any suggestions on how to allow
for these functions of the new version of nlme to be found and used? 

R started exporting a lot fewer functions from base packages
(i.e., making them easily/publicly available).  You can use
getAnywhere() to find out where a hidden method lives, if you don't
know, but in this case I think

nlme:::summary.lmList 

should work.  (For everyday use you shouldn't need to dig out
hidden functions with ::: -- if you have an object of class 'lmList',
then summary(object) should just work.)
