covariance structures in lmer
Hi, I usually use lme from the nlme library. Now I have read an article about lmer in Rnews and lmer seemed to me more comfortable to use. Unfortunately, I didn't find out how to use covariance structures (e. g. corSymm(), corAR1()). Is there a way to use them similarly as in lme ? Is it implemented ? If somebody knows, please let me know. Thank you very much in advance, Stephan

Validating a mixed-effects model
Hi I constructed a mixed-effects model from longitudinal repeated measurements of lab values in 22 patients seperated into two groups with the groups as fixed effect using lme. I thought about using the jackknife procedure, i. e., removing any one subject and calculating the fixed effect, to assess the stability of the fixed effect and thereby validate the model. I suppose this has been done in

R licensing query
I have recently started a new job at an NHS hospital in Scotland. Since I took up this post 6 months ago I have had an ongoing dispute with the IT secutiry dept. who refuse to install R on my computer. I previously worked in another branch of the NHS where R was widely used and yet there is nothing I can say which will persuade the IT dept here to even visit the website! With some help from our

Producing residual plots by time for lme object
Fellow R-users, I have a longitudinal data set with missing values in it. I would like to produce a residual plot for each time using panel.xyplot function but I get an error message.

gam confidence interval (package mgcv)
Dear R-helpers, I am trying to construct a confidence interval on a prediction of a gam fit. I have the Wood (2006) book, and section 5.2.7 seems relevant but I am not able to apply that to this, different, problem. Any help is appreciated! Basically I have a function Y = f(X) for two different treatments A and B. I am interested in the treatment ratios : Y(treatment = B) / Y(treatment = A) as

Compatibility issues between Matrix and kml
Hi the list, I am the maintainer of the package kml. I quite often receive some email about a specific bug. The answer is always the same, I tell people to remove the package Matrix, and then kml works fine. I wonder what my code is not compatible with the Matrix package. Here is a (simplified) version of the kml code : --- 8< ------------ library(longitudinalData)

(PR#11231) [Solaris 9 segfault when closiing X11()]
We need to know a great deal more information, and asking on R-devel would be a lot kinder than blaming this on a bug in R (and please use a meaningful subject line). What version of R is this? Precisely what OS (Solaris 9 comes for several architectures)? Assuming you compiled R yourself, what compilers did you use? (And where did you get those from if they are not Sun compilers?) If got a

add'l info: x86_64 reproducible server PANIC with latest kernel
I forgot to mention that the problem has nothing to do with the kernel being tainted (due to VMware server). I installed VMware server after being faced with the crashes, to give the Java user a "sandbox" which s/he could crash without taking down the real server. Only then I discovered that VMware server has a memory limitation to 3600MB (I guess because it's not a 64bit
