David Moya on 24 Apr 13R es usado sobretodo para crear programas que realicen estadisticas, ya que fue creado para ello principalmente. Con el se pueden hacer análisis estadísticos, predicciónes, modelos... Tiene herramientas que permiten usar poco código para programar estas estadisticas y modelos. Además es un proyecto libre por lo que puedes tener acceso al código fuente y mejorarlo. Gracias a esto y a la gran comunidad que tiene, actualmente es de una gran calidad y tiene disponibles varios "add-on packages".

R is a programming language: you do data analysis in R by writing scripts and functions in the R programming language. R is a complete, interactive, object-oriented language: designed by statisticians, for statisticians.

R is data analysis software: data scientists, statisticians, analysts, quants, and others who need to make sense of data use R for statistical analysis, data visualization, and predictive modeling.

R has benefited for over 15 years from the "many-eyes" approach to code improvement, and as a result has an extremely high standard of quality and numerical accuracy.

you can download and use R for free, but the source code is also open for inspection and modification to anyone who wants to see how the methods and algorithms work under the covers.

R is an environment for statistical analysis: Available in the R language are functions for virtually every data manipulation, statistical model, or chart that the data analyst could ever need. Not only are all the "standard" methods available, but because most cutting-edge research in statistics and predictive modeling is done in R, the latest techniques are usually available first in the R system.

R was first created by Ross Ihaka and Robert Gentleman at the University of Auckland in 1993, and since then the project leadership has grown to include more than 20 leading statisticians and computer scientists from around the world. In addition, thousands of others have contributed additional functionality to the R language by creating add-on "packages" for use by the 2 million users of R worldwide.
