...l by specifying the x and y coordinates on the graph. Then to plot the second label next to it, I am using te strwidth function to get the width of the previous label in user coordinate then add the maximum width to the x value. However, this is not working: Here is an example: lab1<-c("Hocine & Ruba 2000", "Yasmine 2004","Ziad was born in 2006") lab2<-c(20,22,45) lab3<-c(54677,10900,200) plot(-10:5,1:6) text(par("usr")[1],2:4,lab1,adj=c(0,0.5)) text(par("usr")[1]+max(strwidth(lab1)),2:4,lab1,adj=c(0,0.5)) However, this is not work...

Hi Everyone, I am using R 2.10.1. lmer function works properly, however pvals.fnc () does not despite the fact that I uploaded: - library(lme4) - library(coda) - library(languageR) This is the error message I get pvals.fnc(lexdec3.lmerE2, nsim=10000)$fixed Error in pvals.fnc(lexdec3.lmerE2, nsim = 10000) : MCMC sampling is not yet implemented in lme4_0.999375 for models with random

Hello, Has anyone written R functions for applying self-controlled case series methods (http://statistics.open.ac.uk/sccs/). In fact only thing needed is to modify glm function to allow absorption of effect. Eg. in Poisson model individual effect is used as factor, but it is considered as nuisance term where parameter estimates are not needed. Could anyone point how absorbing individual

...Does anyone know if there is a command in R similar to "xtpoisson" in STATA? I want to fit a conditional fixed-effects Poisson model and maximize a conditional likelihood, so I need something similar to "clogit" which is used for logistic regression models. Many thanks Mounia Hocine [[alternative HTML version deleted]]

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML
