I'm getting a memory error while attempting to cluster a large dataset.  I increased the memory to 2G in the info.plist file on my mac, but this failed to solve the problem.  My dataset has 45k rows.  Is there a feasible work-around? If I try a computer w/ more memory, would that solve the problem? 
Thanks for your help!
