extracting r-sq from lme model

Deviance is not reported directly for lme nor can it be extracted using the
deviance() function. How do I work out the deviance or can I work out R-sq
in some other way?

box and whisker (PR#13821)
In a Box and Whisker plot, I thought that when there are outliers both abov=

When I try to use this I get an error

However my machine has 2GB of memory and without R running I only have

Why doesn't outer work?
...lculation is correct but the Pmatrix calculation
gets some of the answers wrong. The final lines of code test the functions.
Any advice on what's going wrong would be greatly appreciated, also any tips
for speeding up the code would fantastic.
Many thanks
