ggplot2 is an open-source data visualization package for the statistical programming language R.Created by Hadley Wickham in 2005, ggplot2 is an implementation of Leland Wilkinson's Grammar of Graphics—a general scheme for data visualization which breaks up graphs into semantic components such as scales and layers. ggplot2 can serve as a replacement for the base graphics in R and contains a ...
Hadley Alexander Wickham (born 14 October 1979) is a New Zealand statistician known for his work on open-source software for the R statistical programming environment. He is the chief scientist at Posit PBC and an adjunct professor of statistics at the University of Auckland , Stanford University , and Rice University .
The tidyverse is a collection of open source packages for the R programming language introduced by Hadley Wickham [1] and his team that "share an underlying design philosophy, grammar, and data structures" of tidy data. [2] Characteristic features of tidyverse packages include extensive use of non-standard evaluation and encouraging piping. [3 ...
In August 2012, Hadley Wickham, Winston Chang, and Garrett Grolemund joined Posit (at the time RStudio Inc.). Wickham was known for working on packages such as ggplot2 and plyr. Chang was known for also working on ggplot2, and publishing the book R Graphics Cookbook. Grolemund was known for working on the lubridate R package, which makes ...
This book also served as the foundation for the R package ggplot2, [8] the Python Bokeh package, [9] the R package ggbio, [10] the Vega declarative language, and helped shape the Polaris project at Stanford University.
RKWard is a transparent front-end to the R programming language, a scripting-language with a strong focus on statistics functions. RKWard tries to combine the power of the R language with the ease of use of commercial statistical packages.
