[R] Confirmatory Factor Analysis

Dear Laura,

In the current version of the Rcmdr package, output of "fit indices" beyond
the LR test, AIC, and BIC is optional, and is controlled by the fit.indices
argument to the summary() method (see ?summary.objectiveML) or by the
fit.indices option. Everyone seems to have different preferences for fit
indices and allowing each person to choose seemed preferable to just
printing them all out.

I hope this helps,
