apparently there is already a namespace for ROC. so
whenever you need disambiguation and want to select the
function defined in ROC, use ROC::f
where "f" names a function in ROC package, and "f" is
also used in another package on the searchlist.

we can use name spaces. i will try to put one in for ROC ASAP.

The name conflicts in Epi and ROC packages (2 'ROC' functions are the
problem) cause the following code
to work once, but not twice:
library(MASS); data(cats);
x = cats[,2]
y = ifelse(cats[,1]=='F',0,1)
library(Epi); ROC(x,y,grid=0)$AUC
library(ROC); AUC(rocdemo.sca(y, x, dxrule.sca))
