R help - Sep 2012 - Package for comparing sensitivity, specificity, PPV, NPV, and accuracy?

Hi, I have two sets of sensitivity, specificity, positive predictive
value, and negative predictive value, and accuracy from two tests on
the same subjects. Is there an R package that does such paired
comparisons?

Thanks,
Gang Chen

Watch out - these are all improper accuracy scoring rules, so statistics
computed on them are likely to be misleading.
