title: tidyr / dplyr performance: CRAN R vs. MRAN Microsoft R Open
body: <p>When I read about Microsoft R Open I ususally read that it is faster in matrix calculations that R from CRAN due to multicore support. </p>
  
  <p>I understand that this can increase performance e.g. when running regressions. Does it also significantly increase calculations from tidyr or dplyr? The underlying question is, i guess, whether these packages rely on matrix calculations or not. More generally, do data.frames work with matrix calculations under the hood? As far as I know, data.frames are a special kind of a list...</p>
  
  <p>Does anyone have an answer to this. Theoretically ans (ideally) some benchmarks?</p>
