[R-SIG-Mac] lme4 print and summary errror

[Andrew Beckerman]

I just wanted to update on this issue, and it appears to be a mac  
problem. I sorted the issue by deleting my .RData and .RHistory files  
in my home directory.  It appears that somewhere in those files,  
perhaps a latent image of something linked to nlme remained, causing  
the print and summary function not to work (on the last three releases  
of lme4).  Having done this, all is well in R+lme4+OSX.  Why this  
happend, I don't know.

Cheers
