[R] classification accuracy in logistic regression

[David Kaplan]

Hi all,

I'm looking for a program that will take the predicted probabilities 
from a logistic regression using glm{stats}, dichotomize them according 
to a threshold that I can control, and then use them to form 
sensitivity, specificity, false pos and false neg rates.

Thanks in advance.

David
