How do you stop R from putting up a dialog box when you quit Rgui? (I use Windows and I never save workspaces that way) Murray -- Dr Murray Jorgensen http://www.stats.waikato.ac.nz/Staff/maj.html Department of...

I'm wondering if a mixed model approach would be useful for estimating large variance-covariance matrices from a modest number of observations. Does anyone have any references on this? Cheers, Murray Jorgensen -- Dr Murray Jorgensen http://www.stats.waikato...

Hi, I'm wondering if anyone has written a function to calculate the likelihood ratio p-values for fixed effects corresponding to the Wald p-values in the fixed effects table in the model summary? Just being lazy! Murray -- Dr...

I want to interlace two vectors. This I can do: > x <- 1:4 > z <- x+0.5 > as.vector(t(cbind(x,z))) [1] 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5...

Hi, I am revising a paper that I am a co-author of. The figures are plots generated from R but at the moment I do not have the R code that generates them. As this is time critical I...
