I've been using the pROC package in R to generate bootstrapped confidence intervals for SP and SN values corresponding to specific thresholds. However, I've been unable to find a way to generate CI's for PPV and NPV values. Does such a function exist inside pROC?

    It would be a lot easier to help if you at least posted a [reproducible example](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) with sample data that calculates PPV and NPV – MrFlick Aug 05 '14 at 22:20

Yes, you can use ci.coords. Type ?ci.coords for more information.
