Hadley Wickham is known for authoring 63 R packages, collectively known as the "HadleyVerse". These packages cover a wide range of topics including data import, manipulation, visualization, and developer tools. Separately, Brian Ripley and Dirk Eddelbuettel are also known for authoring R packages, with 26 and 41 packages respectively under their names ("RipleyVerse" and "DirkVerse"). While presented as a lighthearted comparison, Hadley Wickham has authored the largest number of influential R packages that are widely used.
