R and RStudio Overview
R is a programming language and environment for statistical computing and graphics. The R environment provides an integrated suite of software facilities for data manipulation, calculation, and graphical display. R can import and export data in a variety of formats, both open source and proprietary, including plain text and comma-separated values (CSV), Excel spreadsheets (.XLS and .XLSX), files from a variety of statistical packages (including SAS, SPSS, and Stata), and more.
RStudio is an open-source user interface for R, and it also provides access to some packages not available in the basic R environment.
R and RStudio are useful for a wide variety of data manipulation, analysis, and visualization tasks. Because it is open source and uses literate programming (combining content and code), R facilitates research reproducibility.
