[R] cant get colAUC to plot

[Tuszynski, Jaroslaw W.]

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.

the colAUC function will plot.

Many thanks again
