The Social Dynamics of the R Core Team

August 12, 2012 | John Myles White

Recently a few members of R Core have indicated that part of what slows down the development of R as a language is that it has become increasingly difficult over the years to achieve consensus among the core developers of the language. Inspired by these claims, I decided to look ... [Read more...]
