In this episode of the R-Podcast I have a conversation with my colleague Will Landau about his new R package drake (https://cran.rstudio.com/web/packages/drake/) that provides a powerful build system for analysis pipelines. In addition we have a fun R community roundup, listener feedback, and a couple of package picks to give you a gentle nod and a fun way to explore interpolation. If you have ideas for topics, questions, or other types of feedback, get in touch with me by heading over to the R-Podcast site at www.r-podcast.org (https://www.r-podcast.org), sending a note to thercast[at]gmail.com, or contacting me at @thercast on Twitter. As always thanks for tuning in and I hope you enjoy episode 22 of the R-Podcast!
