plot mean and standard deviation of ROC curves #78

Dear plotROC maintainer,

Thanks for maintaining this tool! The package works great in ploting a single ROC curve. I have a small question about multiple ROC curves.

Say I have 100 test datasets (they are repetitive experiments), each of them can generate a ROC curve, I was wondering if I can use plotROC/geom_roc to aggregate them into one ROC plot, with the curve representing the mean and shadowing (or range bar) representing the confidence interval/standard deviation? Or do you have any comments on how to make this plot in ggplot2?

Thanks,

Hi Wenbin,

No that is not something that plotROC can do. If you aggregate yourself and have the "mean" ROC curve calculated as a data frame with one column for the FPF and one column for the TPF you can plot it using geom_roc with stat = "identity"

See this section of the vignette for an example of plotting a precalculated ROC:

For error bars or ranges I would probably use geom_ribbon()

Hope that helps.

Best wishes, Michael
