ggroc with several aesthetics about proc HOT 3 CLOSED

Am I understanding it correctly that the problem is not about multiple curves in a single ggroc plot, but about changing multiple aestetics? I edited your question to reflect that, if it's not the case please let me know.

This sounds like a good idea, I will gave it a try.

Yes, i guess you are right... It is straightforward to plot many roc curves in the same figure, but my question is merely how to distinguish them. For instance, in a paper it is common that you need different color but also different linetype, in order to be distinguishable also in a black&white paper...

Ps I just tried to change the title in the legend, but it doesn't work...It keeps outputing the title "name" ! See the pic below and the code i tried (myplot is the ggroc object)!

`myplot + guides(fill=guide_legend("my awesome title")) + theme(legend.position="bottom", legend.title = element_text(colour="blue", size=10, face="bold"))` 

Thanks!

It should now be possible to pass multiple values to aes with the latest commit on the master branch:

ggroc(list(rocs...), aes= c("linetype", "colour"))

Please let me know if it works for you.
