Hadley Wickham Toggle navigation Hadley Wickham Teaching Code Personal Hi! I'm Hadley Wickham, Chief Scientist at RStudio , and an Adjunct Professor of Statistics at the University of Auckland , Stanford University , and Rice University . I build tools (computational and cognitive) that make data science easier, faster, and more fun. I’m from New Zealand but I currently live in Houston, TX with my partner and two dogs. Teaching If you’d like to learn more about what I do, and how to use R effectively, I’d recommend starting with one of my books: R for Data Science , with Garrett Grolemund, introduces the key tools for doing data science with R. ggplot2: elegant graphics for data analysis shows you how to use ggplot2 to create graphics that help you understand your data. Advanced R helps you master R as a programming language, teaching you what makes R tick. R packages teaches good software engineering practices for R, using packages for bundling, documenting, and testing your code. I also teach in person workshops from time-to-time; see the RStudio workshops page for more details. Code Most of my work is in the form of open source R code, which you can find on my github . You can roughly divide my work into three categories: tools for data science, tools for data import, and software engineering tools. Data science ggplot2 for visualising data. dplyr for manipulating data. tidyr for tidying data. stringr for working with strings. lubridate for working with date/times. Data import readr for reading .csv and fwf files. readxl for reading .xls and .xlsx files. haven for SAS, SPSS, and Stata files. httr for talking to web APIs. rvest for scraping websites. xml2 for importing XML files. Software engineering devtools for general package development. roxygen2 for in-line documentation. testthat for unit testing Personal Outside of work, I love to bake and make cocktails. You might enjoy trying some of the recipes from my family recipes website . My sister Charlotte is a Assistant Professor of Statistics at Oregon State University. hadley@rstudio.com @hadleywickham 1719 Drew, Houston, TX 77004
