displaying multiple ROC curves on the same graph

[cornel]

Can multiple ROC curves (from different models) be displayed on the same graph ? This did not work for me despite trying on multiple pc's.

I tried to also uncheck the "Advanced Graphics" in setttings. In this case rattle hangs, and the main R console gets this error message:

"Error in as.double(y) :
  cannot coerce type 'S4' to vector of type 'double'"

Hi Cornel,

That is now fixed in Version 3.5.5

> install.packages("rattle", repos="http://rattle.togaware.com", type="source")

Thanks for reporting the bug.

This is awesome, multiple ROC curves can be displayed on one graph  (after unchecking Advanced Graphics, which is also great because it gives both options - all plots on one graph or separate).
