...e... The short form of my main question is: how do I extract variance components from an lme object? The longer form (plus optional supplementary question!): I'm looking at some quantitative genetics, and want to estimate two variance components so that I can then calculate a statistic called Qst from them. So I have this: reg1 <- lme(y ~ temp*food, random =~1|POP/SIRE/DAM, na.action=na.exclude)) summary(reg1) which shows me the random effects as standard deviations. I then want the SIRE and POP variance components (as Vsire and Vpop respectively) to put into the calculation of Q...

...replace=TRUE), q2=sample(1:5, size=10, replace=TRUE)) # Generate a corresponding recodes dataset recodes <- reshape(main, idvar="id", direction="long", varying=list(2:3), v.names="value", timevar="qst") recodes <- recodes[sample(seq(nrow(recodes)), 10, replace=FALSE),] recodes$value <- recodes$value + sign(runif(1)-0.5) I could easily use a for() loop to update the main dataset. The recodes dataset can get quite large, however, so I would rather avoid this. The q...

Hi folks, I have assumed that ratios of variance components (Fst and Qst in population genetics) could be estimated using the output of mcmcsamp (the series on mcmc sample estimates of variance components). What I have started to do is to use the matrix output that included the log(variances), exponentiate, calculate the relevant ratio, and apply either quantil...

Hi R users I need to estimate, with kaplan Meier methodology, a Quality adjusted survival analysis. It is possible doing this at R? Thanks in advance.
