Hi R-colleagues.

I have been using the sem(sem) function.  It uses
maximum likelyhood as optimizing. method.
According to simulation study in Umeå Sweden
Sorry it is in swedish, except the abstract)
maximum likelihood is OK for large samples and normal distribution
the SEM-problem should be optimized by GLS (Generalized Least Squares).

So to the question:

Is there any R-function that solves SEM with GLS?
