Error when running with plot=TRUE

[s2hui]

Hello,

When I execute SCCAF_optimize_all() with plot = TRUE, it will eventually seem to hang after plotting the ROC plots. I have to close the figure window inorder to gain back control of the terminal and then the run terminates with an error (see below). I am not sure what the problem could be.

Thanks for your help,
shui
