Hadley Wickham
Hadley Wickham is the Chief Scientist at RStudio, a member of the R Foundation, and Adjunct Professor at Stanford University and the University of Auckland. He builds tools (both computational and cognitive) to make data science easier, faster, and more fun. You may be familiar with his packages for data science (the tidyverse: including ggplot2, dplyr, tidyr, purrr, and readr) and principled software development (roxygen2, testthat, devtools, pkgdown). Much of the material for the course is drawn from two of his existing books, Advanced R and R Packages, but the course also includes a lot of new material that will eventually become a book called “Tidy tools”.
Maintaining the house the tidyverse built
January 21, 2021
A talk about how the tidyverse has evolved since its creation (just five years ago!).
testthat 3.0.0
August 13, 2020
In this webinar, I'll introduce some of the major changes coming in testthat 3.0.0. The biggest new idea in testthat 3.0.0 is the idea of an edition.
vctrs: Tools for making size and type consistent functions
January 25, 2019
vctrs is a new package that provides tools (cognitive and computational) to ensure that functions behave consistently with respect to inputs of varying length and type. The end goal of vctrs is...
What's new in dplyr 0.7.0
June 22, 2017
dplyr provides a “grammar” of data transformation, making it easy and elegant to solve the most common data manipulation challenges.
Collaboration and time travel- version control with git, github and RStudio
April 14, 2016
Hadley Wickham presents and demonstrates how understanding git & github will give you two data science superpowers.
Getting Data into R
January 28, 2016
You can’t use R for data analysis unless you can get your data into R. Getting your data into R can be a major hassle, so in the last few months Hadley Wickham has been working hard to make it easier.
