[R] Organizations where IT has approved the use of R software

Hi Gang, I realize this post is not directly related to programing issues with R, however, it appears this may be the best place to ask my question. I am putting forward a request that R be considered approved software in my organization. Never an easy task, this is made much more difficult

[R] Extended beta-binomial model in R

Dear all, I have been searching far and wide for a solution to the problem of negative intracluster correlation in the case of a binomial response variable (also known as under-dispersion). Prentice (1986) (http://www.jstor.org/stable/2289219) developed an extension of the beta-binomial model

[R] Simple Problem: Plotting mathematical functions

Hey there, I want to plot 5 parabola functions, which happen to be f(x) = 0.25x² + 6,47x -32.6 g(x)=0.99x² -6x -195 j(x)= 0.77x² +14x -495 k(x)=0.001x² + 65x -785 l(x) = 0.9x² -2x -636 in the same graph. Sadly I even do not really understand how to plot just one

Welcome to R and the list. Others may suggest books ( Nutshell was my first ) but first there are some things that will help you both in programming and getting help on the list. You should post executable code in your question. So, build a toy example of the data.frame you have and show

Very interesting book! However, it doesn't cover multivariate models (I have 9 moderately correlated, categorical dependent variables). Again, I'm trying to find out whether 5 time-varying variables (dichotomous; five different life events yes/no; subjects can have several life events at the same
