lme fitted correlation of random effects: where is it?
The print method for lme *prints out* the fitted correlation matrix for
the random effects. Is there any way to get these values as an object in
R? I have examined the components of the lme object (called "junk" in the
example below) and the components of summary(junk) without finding these
numbers.
(How I did this: I dumped the entire lme object to a text file and then
used egrep to

Extracting elements from an reStruct

equation, and residual is the residual variance. The problem is getting
access to var1..varn (or, as R generally reports it, sd1..sdn)
programmatically. I can get the residual standard deviation with:
print(model$sigma)
and I can view the standard deviations with:
summary(model$modelStruct$lmeStruct)
But I can't figure out how to get at the standard deviations without the
human-readable print format.
Thanks-

Predicting a single observatio using LME
When I use a model fit with LME, I get an error if I try to use "predict" with a dataset consisting of a single line.
For example, using this data:

Fixed effects
Hello everyone!
I would really appreciate it if someone knew where could I find the command
in R in order to run a fixed effects regression.
What format should my data have?
I have looked through the manual and I could not find anything
Thank you in advance,
Petros

Individual log likelihoods of nlsList objects.
Hello all.
I was wondering if the logLike.nls() and logLike.nlme() functions are still
being used. Neither function seems to be available in the most recent
release of R (1.9.1). The following is contained in the help file for
logLik(): "classes which already have methods for this function include:
'glm', 'lm', 'nls' and 'gls', 'lme' and others in
