After 15 years working on S-PLUS, I've moved over to Mango Solutions. I'm one of the founders of the Swiss subsidiary Mango Solutions AG, which is based in Basel. Mango is a data analysis consulting firm that does a lot of work with R and Java, so the nature of my work hasn't changed dramatically.
I'll update the "About the Author" box on the right whenever I manage to find the "Layout" tab in the blog management interface. It seems to have gone missing for this blog.
Charles Roosen has been an S user since 1991, when he started with the Bell Labs version of S on a DEC at Stanford. Between 1995 and 2008 he worked on the development of S-PLUS. Currently he is a Technical Director at Mango Solutions AG.
