I used the ROC library in the past and it worked very well. Now I immediately
get the following
error message and I don't know what the problem is. Can anyone help? (S-Plus
6-release 2).
Thanks.
> roc(V1 ~ V2, data = tryout)
the "..." object should be a list but has mode "missing"
Problem in NextMethod("model.matrix", data = data, ..: argument "..1" is
missing with no default
