I think I solved the problem =) My dataset is an .arff file. So I read my data into R via read.arff. I tried the following: Export the dataframe to an txt-file and import it once again in R via read.table. With the new dataset if works fine. Maybe the error comes from the variable-names. I attached a txt-file containing the str(traindat.bin) output from the data.frame, which I import via read.arff

Can you reduce the data.frame in a way (less variables and observations) so that you can send the rest by e-mail and we can see the error?
