Hi,
I'm using the sem package under conditions where I know beforehand that
several models will be problematic. Because of that, I want to suppress
warnings. I've used the following code
sem(mod, S = as.matrix(dataset), N = 1000, maxiter = 1,
warn = FALSE)
But I still get warning

Sure, something like that. Store each model as an element of a list,
and then use something like
for(i in 1:4){
indices<-combn(1:4, i)
for (j in 1:length(indices[1,])){
new.model<-combine.models(model.pieces[ indices[,j] ] )
#code for analysis
}
Jarret,
I've donwloaded the zip file and installed, but maybe have lost some
pre-req check. I have manually installed sna.
Anyway, which would be the approach you suggest? Making (using my
example) 4 different models, one for each construct, then use
combine.models and add.to.models to create the
install.packages("sem-additions",repos="http://R-Forge.R-project.org";)
Sorry, it's sem-additions on r-forge. Not sem.additions, which is
what I had originally called it. But they won't take . in the name of
a package.

Ivan,
I recently put together the sem.additions package over at R forge in
part for just such a multiple model problem. THere are a variety of
methods that make it easy to add/delete links that could be automated
with a for loop and something from the combn package, I think.

hi,
I plot path diagrams with the path.diagram() function of the sem

Now I want the graphviz code for a path-plot with the actual
standardized coefficients on the arrows (not the names).
I tried to add edge.labels="values" as an argumen
Hi John-
Thanks. You were right--AMOS was not reading the sample size correctly
(i.e., I was not telling it correctly). When I corrected the problem, I
got the same estimates. Thanks for pointing me in the right direction.

Dear Anthony,
sem() does FIML estimation, not 2SLS, and so it's hard to understand
why you're getting "nearly identical" parameter estimates but very

I am using R to build my initial models, but need to use AMOS to compare

Hello-
If I input a variance-covariance matrix and specify NA for start values,
how does sem determine the start value? Is there a default?
