His sister, Charlotte Wickham, is also a statistician, data scientist and educator. She taught in the Statistics Department at Oregon State University between 2011 and 2022,[5] and currently works for Posit PBC on the developer relations team.[6] She holds a first-class honours bachelor of science degree in Statistics from University of Auckland and a PhD in statistics from University of California, Berkeley.[7]
He is a prominent and active member of the R user community, and has developed several notable and widely used packages including ggplot2, plyr, dplyr and reshape2.[11][12] Wickham's data analysis packages for R are collectively known as the tidyverse.[13] According to Wickham's tidy data approach, each variable should be a column, each observation should be a row, and each type of observational unit should be a table.[14]
Honors and awards
In 2006 he was awarded the John Chambers Award for Statistical Computing for his work developing tools for data reshaping and visualisation.[15] Wickham was named a Fellow by the American Statistical Association in 2015 for "pivotal contributions to statistical practice through innovative and pioneering research in statistical graphics and computing".[16] Wickham was awarded the international COPSS Presidents' Award in 2019 for "influential work in statistical computing, visualisation, graphics, and data analysis" including "making statistical thinking and computing accessible to a large audience".[17]
