While I was in LA for the useR! 2014 conference last month, I had the great pleasure of being among the participants in the DataScienceLA interview series hosted by Eduardo Ariño de la Rubia. Eduardo is both an R user and an excellent interviewer: his preparation and knowledge of R has resuled in a fascinating interview series for any R user.
Eduardo has a detailed summary of our interview on the DataScienceLA blog, and I've also embedded it to watch below.
Be sure to check out Eduardo's other interviews with Tal Galili (creator of R-bloggers.com), Hadley Wickham (chief scientist, RStudio) and Max Kuhn (author of the caret package) and to follow DataScienceLA on Twitter to be notified of further interview in the series.
