An Introduction to R
R can be regarded as an implementation of the S language which was developed at Bell Labora-tories by Rick Becker, John Chambers and Allan Wilks, and also forms the basis of the S-Plus systems. The evolution of the S language is characterized by …
All resources are available from this page: the R system itself, a collection of add-on packages, manuals, documentation and more. The intention of this chapter is to give a rather informal introduction to basic concepts and data manipulation techniques for the R novice.

Section 2: What is R? 2.1 — History The R programming language is an offshoot of a programming language called S. It was developed by Ross Ihaka and Robert Gentle-man from the University of Auckland, New Zealand. It was primarily adopted by statisticians and is now the de facto standard for statistical computing.
Learning objectives: Install and load R packages Find package and function documentation Load external data into R Create and query vectors, matrices, and data frames Compute descriptive statistics and regression models Construct basic graphical displays.
R is a system for statistical analyses and graphics created by Ross Ihaka and Robert Gentle-man1. R is both a software and a language considered as a dialect of the language S created by the AT&T Bell Laboratories. S is available as the software S-PLUS commercialized by Insightful2.
R is a statistical analysis environment initially created and developed by Ross Ihaka and Robert Gentleman in 1996. It can be regarded as an implementation of the S language, which was developed at Bell Laboratories by Rick Becker, John Chambers and Allan Wilks.
