Can someone please explain why this wont plot. The cats example given for the colAUC function will plot.

It is a bug, I will have to fix. I assumed that data will have column names I can use for legend. So temporary fix is to provide column names: library(caTools) a<-matrix(rnorm(100), 100,1) b<-rbinom(100,1,0.7) colnames(a) = "test"; colAUC(a,b,plotROC=TRUE) Thanks for reporting it.
