[DSC 4.0] What Makes a Good Function - Hadley Wickham keynote

What makes a function hard to use? What makes a function easy to use?
In this talk, we discussed about some big ideas about the design of functions by first looking at the what makes a door easy to use, and then showing some examples of what makes a function hard to use.
This talk was presented by Mr. Hadley Wickham, Chief Scientist at R Studio, during Data Science Conference 4.0, as a keynote talk.

He should get a Nobel Prize for tidyverse "For Bringing Data Analysis to the Masses" like at 40:15

Update: and he did. Won the "Nobel Prize for Statistics" (COPSS award 2019) for "making statistical thinking and computing accessible to a large audience"

his responses are very intelligent...he clearly spends a lot of time thinking through the conceptual aspects of a problem.

nice talk. I like the way in the end Hadley seemlessly types code on mtcars. So incredible.
