Wickham 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.[8][9] Wickham's data analysis packages for R are collectively known as the tidyverse.[10] 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.[11]
