Agreed about Hadley&#x27;s prolific work.<p>I used to work a lot with R many years ago. I was shocked to find how bad the documentation was, and worse how rude and unfriendly the &quot;community&quot; of grumpy professors was. I shudder to think of the horrible meanness towards beginners asking questions on the mailing list.<p>I got so fed up I even wrote a book about R data visualisation. But this was all just around the time ggplot2 came out. Unfortunately I stopped using R soon after, but since then Hadley has single-handedly done more good for the language than anyone else.<p>I don&#x27;t know what the R community is like now, and whether people like Hadley have made it friendlier, but it&#x27;s clearly one reason Python is superior.
