title: Recommended package for very large dataset processing and machine learning in R
body: <p>It seems like R is really designed to handle datasets that it can pull entirely into memory. What R packages are recommended for signal processing and machine learning on very large datasets that can not be pulled into memory? </p>
  
  <p>If R is simply the wrong way to do this, I am open to other robust free suggestions (e.g. scipy if there is some nice way to handle very large datasets)</p>
