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?

This is really a preliminary test. Feel free to

When I try this, column ddd has 1 fewer digits than expected. See the

Why don't all the columns have the same number of digits displayed?

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 pair...
