structural equation modeling
...am interested in using structural equation modeling.
Just getting started with it, but I'm looking for suggestions for packages.
As an aside, what's the best way for looking for packages at CRAN?

Google Custom Search Engine for R
Hi,
Since "R" is a (very) generic name, I've been having some trouble

In my data, twin pair ID is the clustering variable; correlations are
expected to be exchangeable but substantially different between members of
monozygotic twin pairs and members of dizygotic twin pairs. Hence, in my
analyses, the variable that's "outer" to twin pai...
