Neeti, I'm pretty sure that the error is related to the confusionMAtrix call, which is in the caret package, not e1071.
The error message is pretty clear: you need to pas in two factor objects that have the same levels. You can check by running the commands: str(pred_true1) str(species_test) Also, caret can do the resampling for you instead of you writing the loop yourself.
