Hi,


Is it possible to get ROC and accuracy ratio/gini straight out of the
Design package?


Thanks

The print method for lrm prints the ROC area (labeled "C").  lrm does 
not print the other 2 measures you listed.  It computes a generalized 
R^2 (much more powerful than all the other measures) and rank indexes 
other than C.
