      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
  • ...7 more annotations...
  • 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.
  • Here is the list of useR! conference: useR! 2004, Vienna, Austria useR! 2006, Vienna, Austria useR! 2007, Ames, Iowa, USA useR! 2008, Dortmund, Germany useR! 2009, Rennes, France useR! 2010, Gaithersburg, Maryland, USA useR! 2011, Coventry, United Kingdom useR! 2012, Nashville, Tennessee, USA useR! 2013, Albacete, Spain

      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.

      Revolution Analytics es un proveedor comercial de software y servicios relacionados con el lenguaje R. Es un lenguaje de programación basado en estadística que tiene muchos usuarios. Las empresas están recogiendo enormes cantidades de datos, pero a menudo no pueden analizar los mismos debido a problemas de escala. Revolution Analytics ayuda a afrontar estos problemas mediante un nuevo enfoque. "Revolution R" proporciona velocidad y escala en el análisis de grandes datos.
  • Revolution Analytics provides value by taking the most recent release from the R community and adding scalability and other functionality so that R can be implemented and seamlessly work in a commercial environment. Revolution R provides a development environment so that data scientists can write and debug R code more effectively, and web service APIs that integrate with other BI tools and dashboards so that R can work with business intelligence tools and visual discovery tools. In addition, Revolution Analytics makes money through professional and support services.

      Miestra como una empresa puede ofrecer un servicio basado en R como producto.
  • For example, IBM’s PureData System for Analytics (IBM’s new name for its MPP Netezza appliance) uses the in-database approach with an R instance running on each processing unit in the database, each of which is connected to an R server via ODBC. The analytics are invoked as the data is served up to the processor such that the algorithms run in parallel across all of the data.

  • I’ve heard that Revolution R isn’t always the easiest software to use and that the experience isn’t exactly seamless, but it can be argued that in the cutting-edge field of big data analytics a challenging environment is to be expected. If Revolution Analytics can address some of these useability challenges, it may find its pie growing even faster than it is now. Regardless, I anticipate that Revolution Analytics will continue its fast growth (already its headcount is doubling year-over-year). Furthermore, I anticipate that in-database analytics (an area where R really shines) will become the de-facto approach to big data analytics and that companies that take full advantage of that trend will reap benefits.

  • 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."

  • Many people view the end results of all this technology via the Firefox Web browser, also open-source software.
  • R is also the name of a popular programming language used by a growing number of data analysts inside corporations and academia. It is becoming their lingua franca partly because data mining has entered a golden age
  • Companies as diverse as Google, Pfizer, Merck, Bank of America, the InterContinental Hotels Group and Shell use it.
  • R has also quickly found a following because statisticians, engineers and scientists without computer programming skills find it easy to use.
  • Many people view the end results of all this technology via the Firefox Web browser, also open-source software.
  • Most Web sites are displayed using an open-source application called Apache, and companies increasingly rely on the open-source MySQL database to store their critical information. Many people view the end results of all this technology via the Firefox Web browser, also open-source software.
  • For statisticians
  • R is particularly useful because it contains a number of built-in mechanisms for organizing data, running calculations on the information and creating graphical representations of data sets.
  • What makes R so useful
  • is that statisticians, engineers and scientists can improve the software’s code or write variations for specific tasks. Packages written for R add advanced algorithms, colored and textured graphs and mining techniques to dig deeper into databases.
  • The financial services community has demonstrated a particular affinity for R; dozens of packages exist for derivatives analysis alone.
