...ing methods to generate and fit collections of glm models, and handling lists of such model objects, of class "glmlist". The simplest example is fitting all k-way models, from k=0 (null model) to the model with the highest-order interaction. I'm having trouble writing a function, Kway (below) to do what is done in the example below > factors <- expand.grid(A=1:3, B=1:2, C=1:3) > Freq <- rpois(nrow(factors), lambda=40) > df <- cbind(factors, Freq) > > mod.0 <- glm(Freq ~ 1, data=df, family=poisson) > mod.1 <- update(mod.0, . ~ A + B + C)...

...diagrams (sieve) for these models. See demo("mental-glm"), demo("vision-quasi") and others. o Some initial steps in collecting, handling and summarizing sets of related glm() and loglm() models provided by the functions glmlist(), loglmlist() summarize() methods, Kway() for fitting all k-way glm() models, etc. -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept.

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
