randomForest: tuneRF error
Since we do not have the data, it is hard for us to reproduce and debug. Uwe Ligges

Just curious if anyone else has got this error before, and if so, would know what I could do (if anything) to get past it:

I've used tuneRF successfully before, but in this instance, no matter
what I change in the parameters, I still get the error above (last
line). The data has no NAs in it. I'm using R 2.12.0 (64bit-M$ Windows
7).
Thanks in advance!
