As the R programming environment has grown in capability and popularity, so have the number of organizations planning to migrate to it from proprietary tools. I’ve helped members of various organizations transition from SAS, SPSS and/or Stata to R (see Workshop Participants), and the process typically involves the following steps:
1) Begin with the most important question: who should you migrate to R? Learning R is not a trivial task (see Why R is Hard to Learn). However, once mastered by people who use it regularly, I think it’s easier to use than other software. But if you have some people who use something like SAS only occasionally and view it as hard to use, you might consider having them try one of the menu-based front-ends to R. If they want to continue using SAS while lowering your licensing costs, you might consider the SAS implementation used in WPS (see World Programming).
