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,
