I was trying to produced bagged importance estimates of attributes in earth
using the caret package with the following commands:
fit2 <- bagEarth(loyalty ~ ., data=model1, B = 10)
bagImpGCV <- varImp(fit2,value="gcv")
My bootstrap estimates are produced however the second command "varImp"
produces the following error:
Error in UseMethod("varImp") : no applicable method for "varImp"
Not sure what is going on, any advice would be appreciated,
Thanks,
Joe Retzer
