“Editorial” published in The R Journal.

On behalf of the editorial board, I am pleased to present Volume 15 Issue 2 of the R Journal.

Behind the scenes, several people assist with the journal operations. Mitchell O’Hara-Wild continues to work on infrastructure, H. Sherry Zhang continues to develop the rjtools package under the direction of Professor Dianne Cook. In addition, articles in this issue have been carefully copy edited by Adam Bartonicek and Chase Robertson.
