roc - Calculate many AUCs in R -


i new r. using rocr package in r calculate auc, can 1 predictor fine. looking perform many auc calculations 100 different variables.

what have done far following:

varlist <- names(mydata)[2:101] formlist <- lapply(varlist, function(x) paste0("prediction(",x,"mydata$v1))

however formulas in text format, , as.formula giving me error. appreciated! in advance!

the function inside lapply looks outputting statement prediction(varmydata$v1). guessing want run command. if so, want 

lapply(varlist,function(x) prediction(mydata[x]))

but hard tell without reproducible situation. also, looks code has missing quote.
