OK, the information I send to the list were rather sparse. Sorry for that! I just tried the command with the recent Version of R and ipred. The error message is the same. I want to create a classification model. My data consist of 5414 observations and 98 variables whereof 33 are numeric, the remainder are binary nominal (factor) variables. My output SOIL_UNIT is a factor variable with 82 levels.
I hope this are enough information to understand the problem.

Please do read the posting guide. - We do not have "traindat.bin", hence cannot reproduce your problem - Does it happen with recent versions of R and ipred?
