R help - Sep 2005 - Probit-normal model and ROC Curve

Dear List,

I have two questions.

First: a longitudinal data set with a gaussian response and a 
dichotomicous one. Could you tell me if there is a function or a package 
to fit a Probit-normal model like Regan and Catalano (1999) or a similar 
model?

Second: Is there a function to plot a ROC Curve, and plot its Confidence 
Bounds?

Thanks in advance

Francisco
