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

memory problems
Hi
I'm computing a bca interval using bca.ci from the boot package.
When I try to use this I get an error
> library(boot)
> boot(logglm.data,boot.fishpower,2500,coef.vec=coeflm.vec)->blm8901
> bca.ci(blm8901,index=29)
Error: cannot allocate vector of size 456729 Kb
However my machine has 2GB of memory and without R running I only have
112M of memory used.
Is there something

Why doesn't outer work?
...trix 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
