  • It's not surprising that Oracle has moved to support R, which "has become a real ubiquitous force in advanced analytics," said Forrester Research analyst James Kobielus. "It's everywhere. Enterprise adoption of it has been growing steadily. When we ask our customers what they're using for statistical modeling they'll say SAS or [IBM's] SPSS, but they increasingly say R in the same breath."

      R 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.
  • R is an open-source software project
  • 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.

      El lenguaje r nos permite realizar una gran cantidad de predicciones de mercado y económicas que nunca antes se habian podido sacar con otros lenguajes o métodos.Este lenguaje es utilizado para la realización de predicciones analíticas que ayudan a entender mejor el mercado , las costumbres y las tendencias de los consumidores...Este además es un lenguaje muy joven todavía, al cual se le puede llegar a sacar una gran potencial.
  • Predictive analytics is statistical modeling by any other name. It's used by statisticians and data analysts across all verticals as a means to better understand their organization, both internally and externally. It helps identify trends and patterns, arming CIOs and other enterprise decision makers with the best possible information with which to make their decisions. Predictive analytics has a proven track record in the business intelligence field. Wal-Mart, for one, has used predictive analytics to better understand the habits and tendencies of their customers.
  • : R is still relatively young and is only just now being recognized outside of academic circles. Its practically limitless statistical capabilities make it attractive to anybody doing data analysis, be they a statistics professor or a financial analyst

      En esta página se señala dónde es necesario utiizar el lenguaje R (compañías que requieran recoger mucha información y analizarla). Se pone por ejemplo la empresa revolution Analytics, que se dedica a crear nuevas herramientas para los usuarios de este lenguaje de programación, en un intento de llegar a más gente y expandir su uso.
  • "Today, R is memory-bound and cannot handle large data sets," Smith said. "So we'll be bringing out in the near future a solution for handling massive datasets in the terabyte and petabyte range."

  • Revolution Analytics is also working on R usability. Smith noted that R, to date, has been a command-line-driven language, which has represented a challenge for some mainstream enterprise users."So we'll be rolling out a modern, flexible and extensible thin client user interface that can bridge the gap between expert users and the more casual business analysts," Smith said.
