KO: What is your name, job title, and how long have you been using R? DS: My name is David Smith. I work at Microsoft and my self-imposed title is ‘R Community Lead’. I’ve been working with R specifically for about 10 years, but I’d been working with S since the early 90s. KO: How did you transition into using R? DS: I was using S for a long, long time, and I worked for the company that commercialized S, where I was a project manager for S-PLUS.
