View the affiliations of R Core members. We’ve left it up to the individual core developers to list areas of expertise (or things they are willing to maintain) if they wish.

The Contributors page on the R Project website also lists contributors, outside the R Core team, who provided invaluable help by donating code, bug fixes, and documentation.
