I am having trouble with the rfImpute function in the randomForest package.
Here is a sample...
clunk.roughfix<-na.roughfix(clunk)
>
> clunk.impute<-rfImpute(CONVERT~.,data=clunk)
ntree OOB 1 2
300: 26.80% 3.83% 85.37%
ntree OOB 1 2
300: 18.56% 5.74% 51.22%
Error in randomForest.default(xf, y, ntree = ntree, ..., do.trace = ntree,
:
NA not permitted in predictors
So roughFix works, but rfImpute doesn't....
Thanks,
Eric
