R Data Analysis and Graphics Computer Programming Language.
I. R INTRODUCTION
R is a computer programming language for statistical computation, data analysis, and graphics developed at Bell Laboratories by John Chambers, and later revised by Robert Gentleman, Ross Ihaka and a host of other core team members and volunteers. R is available as "free software". R has excellent text manipulation capabilities.
II. DOWNLOADING AND INSTALLING R
In the column on the left side of the page, select “Comprehensive R Archive Network” (CRAN) in the "Download Packages" section. During the download, select the option which places an R icon on your desktop.
My computer uses Microsoft Windows; therefore, I used the "Download R 3.1.2 for Windows" and my R download was to the following default hard drive path folder:
C:\Program Files\R
If necessary, check your hard drive and write down and remember the hard drive default path folder your computer used for your R download. You will need to know this default information when you are writing and reading R files.
III. R DOWNLOAD AND INSTALLATION VALIDATION
"Double left mouse click" the R icon on your desktop to start the R console as shown below:
