WHAT IS R?
R is a free, open source software program for statistical analysis, based on the S language.
WHAT IS RSTUDIO?
RStudio is a free, open source IDE (integrated development environment) for R. (You must install R before you can install RStudio.) Its interface is organized so that the user can clearly view graphs, data tables, R code, and output all at the same time. It also offers an Import-Wizard-like feature that allows users to import CSV, Excel, SAS (*.sas7bdat), SPSS (*.sav), and Stata (*.dta) files into R without having to write the code to do so.
WHY USE R?
Free and open source.
Available for Windows, Macintosh, and Linux.
Publication-quality graphs.
Rivals (and in many cases, exceeds) SAS and Stata in terms of availability of advanced statistical methods and algorithms, through availability of user-created packages.
Packages for literate statistical programming - weaving written reports and analysis code in one document.
