Hi,

I am trying to use pROC in RStudio Cloud. The data I'm dealing with can only be accessed in a secure "datalab" environment designed by Statistics New Zealand, so using R on my personal computer is not possible and I doubt that Stats NZ will be able to support a different implementation just for me.

Using the DeLong method to get a confidence interval works no problem, but when I try something like:

ci.auc(roc_object, method = "bootstrap")

I get the error:

Error in structure(.External(.C_dotTclObjv, objv), class = "tckObj") : [tcl] invalid comman name "toplevel".

This appears to me to be similar to this issue in the old RStudio community. It appears that the tcltkpackage is the reason it doesn't work? Is that the case for the pROC package too?

Thanks for the great package, would love any feedback on whether I'm mistaken or whether a work around is possible!
