Hashing and environments
...uickly. But I've never really understood very well how hashing works, so I'm having trouble.
Here is an example of what I've done so far:

setMethod("initialize","Lexicon",function(.Object,wfreqs) {
.Object at e <- new.env(hash=T,parent=emptyenv())
assign("wfreqs",wfreqs,envir=.Object at e)
return(.Object)
})
## function to access word frequencies
wfreq <- function(lexicon,word) {
return(get("wfreqs",envir=lexicon at e)[word])
}

logistic mixed effects models with lmer
I have a question about some strange results I get when using lmer to
build a logistic mixed effects model. I have a data set of about 30k
points, and I'm trying to do backwards selection to reduce the number
of fixed effects in my model. I've got 3 crossed random effects and
about 20 or so fixed effects. At a certain point, I get a model (m17)
where the fixed effects are like this
