Hi, Dear all R users: Does someone know whether R can calculate the Receiver Operating Characteristic (ROC) Curves? I didn't find it from the packages. Thanks a lot. --- Xin
package ROC from bioconductor, eg: bioconductor.org/repository/release1.5/package/Win32 Cheers!

There is a package, Lexis, not officil though, which contains a function ROC (and some other stuff for epidemiology). You can find it in: biostat.ku.dk/~bxc/SPE/library Bendix Carstensen ---------------------- Bendix Carstensen Senior Statistician Steno Diabetes Center Niels Steensens Vej 2 DK-2820 Gentofte Denmark tel: +45 44 43 87 38 mob: +45 30 75 87 38 fax: +45 44 43 07 06 bxc at steno.dk biostat.ku.dk/~bxc ----------------------> -----Original Message----- > From: r-help-bounces at stat.math.ethz.ch > [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of Xin Qi > Sent: Tuesday, November 30, 2004 5:49 AM > To: r-help at stat.math.ethz.ch > Subject: [R] About ROC curves > > > Hi, Dear all R users: > > Does someone know whether R can calculate the Receiver Operating > Characteristic (ROC) Curves?

I didn't find it from the packages.Issue 1 of the R Newsletter this year used ROC curve calculation as an example of simple S3 and S4 classes. -thomas
