Undefined Column Sequence

Hi,

I was trying to do algorithm selection for machine learning data. When building a model the R interpreter makes an error. I pasted my commands as well as the output:

The R interpreter is freshly compiled and runs under Ubuntu 14.04. I tried the ASP benchmark from the ASLIB and it worked without problems.

Hmm, sounds like this is a llama issue and you should open an issue in its repository (https://bitbucket.org/lkotthoff/llama/issues?status=new&status=open). If you send me a sample of the data that allows me to reproduce the error I'd be happy to have a look.

Please excuse me, I posted this into the wrong repository. I will send you an e-mail with the files.
