  • 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."

  • As you can see, for organizations who need to create advanced analytics applications, R is integrated throughout the analytics stack: for data access, for presentation of results, and of course for the statistical analysis process itself. This degree of integration by so many companies is indicative of the level of demand for R throughout the enterprise. As the leading provider of commercial software and support for R, Revolution Analytics supports R users througout the organization,

  • R has been receiving a lot of attention recently, although it’s been around for over 15 years. R is an open-source language and environment for statistical computing and data visualization, supporting data manipulation and transformations, as well as sophisticated graphical displays

  • n contrast, statisticians and data analysts typically don’t know SQL and are not familiar with database tasks. R provides statisticians and data analysts access a wide range of analytical capabilities in a natural statistical language
  • However, there is another issue that limits R’s scalability…
  • R is limited by the memory and processing power of the machine where it runs
  • this chews up memory faster.

      Anualmente se celebra un encuentro para los usuarios que utilizan el lenguaje R. Entre los últimos destinos en los que se han celebrado las reuniones, podemos destacar Rennes, Tennessee o Albacete.
  • R is an interpreted language; users typically access it through a command-line interpreter.
  • R supports matrix arithmetic

  • R's data structures include scalars, vectors, matrices, data frames (similar to tables in a relational database) and lists.
  • R's extensible object-system includes objects for (among others): regression models, time-series and geo-spatial coordinates.
  • Although mostly used by statisticians and other practitioners requiring an environment for statistical computation and software development, R can also operate as a general matrix calculation toolbox - with performance benchmarks comparable to GNU Octave or MATLAB.
  • "useR!" is the name given to the official annual gathering of R users.

      R es un lenguaje basado en el uso de línea de comandos. Soporta matrices, escalares y vectores además de operar estadísticamente. Su cálculo en el ámbito de matrices es comparable a otros softwares como pueden ser Matlab o GNU Octave.

      Hemos elegido consultar la información general sobre R en la versión en inglés de Wikipedia, ya que nos parecía más completa y elaborada. En primer lugar se enumeran las capacidades principales de este lenguaje y algunos de sus principales usos. También se destaca el hecho de que es 'GNU project' y que está disponible bajo licencia GPL. A pesar de ser un lenguaje que utiliza la linea de comandos, se descaca que existen diversas interfaces gráficas para facilitar su uso. En un apartado posterior se enumeran algunas de las principales versiones de estas interfaces. http://en.wikipedia.org/wiki/R_(programming_language)#Graphical_user_interfaces Se destaca en varios de los apartados del artículo la enorme versatilidad y capacidad de adaptación a distintos campos que posee este lenguaje debido a la gran cantidad de paquetes y extensiones que soporta. También se indica que debido a su herencia del lenguaje S, está más dirigido a la programación orientada a objetos que la mayoria de lenguajes estadísticos. Finalmente se destaca el uso comercial que se le ha dado a este lenguaje, y encontramos ejemplos como el de Oracle y el de Revolution Analytics.
