similar to: Revolutions Blog: January 2014 roundup

Since 2008, Microsoft (formerly Revolution Analytics) staff and guests have written about R at the Revolutions blog (http://blog.revolutionanalytics.com) and every month I post a summary of articles from the previous month of particular interest to readers of r-help. In case you missed them, here are some articles related to R from the month of December: Hadley Wickham's Shiny app for making

Hi, This problems has bothered me for the lase couple of hours. > 1e-100==0 [1] FALSE > (1-1e-100)==1 [1] TRUE How can I tell R that 1-1e-100 does not equal to 1, actually, I found out that > (1-1e-16)==1 [1] FALSE > (1-1e-17)==1 [1] TRUE The reason I care about this is that I was try to use qnorm() in my code, for example, > qnorm(1e-100) [1] -21.27345 and if I want to

Hi Gang, I realize this post is not directly related to programing issues with R, however, it appears this may be the best place to ask my question. I am putting forward a request that R be considered "approved" software in my organization. Never an easy task, this is made much more difficult given that it is open source software (sends the IT gang into little fits). So, I am

Buenas, Alguno ha probado a usar Microsfot R Open?

We were also able to reproduce the issue on Windows Server 2012.

Has anyone heard whether Revolution Analytics is going to release this capability to the R community? http://www.businesswire.com/news/home/20110201005852/en/Revolution-Analytics-Unlocks-SAS-Data Dan Daniel Nordlund Bothell, WA USA

Dear users, The company where I work is considering getting a license for Revolution Enterprise - Windows 64-bit. I'll appreciate for those familiar with the product if can share your experiences with it? In particular, how does it compare to the "free" version of R 64-bit? Thanks in advance. Regards, Lars.

Hi, I am trying to get R installed at work and I was asked if there were any companies that offered support. After searching on Google (many ways) and not find anything, I turn to you. BTW, I did see Revolution R supports their flavor. Thanks, Chris [[alternative HTML version deleted]]

Buenos días: Un saludo a todos y a todas. Quisiera consultaros acerca del grado de uso de R en España y en el mundo. He leído, por ejemplo, que es posible integrar el uso de R en herramientas de Business Intelligence (Microsoft Sql Server, Reporting Services), pero ¿realmente se utiliza esa integración?. Y, en general, ¿qué grandes empresas utilizan R y para qué?. También preguntar si tenéis

Hola! Quiero empezar a georeferenciar en mapas con R. En blogs se encuentra bastante información pero veo que no hay unanimidad respecto a las librerías a utilizar ni tampoco la información es muy clara ni abarcativa. ¿Alguno/a trabaja con mapas en R y me puede indicar por donde encarar? En principio mi interés es realizar mapas sencillos con información por provincias y departamentos de

Estimados Hace un tiempo pregunte por un problema con neuralnet, hoy instale R desde https://mran.revolutionanalytics.com/ y el problema anterior fue solucionado por sus desarrolladores, pero me asombre por un cambio en la velocidad (no use un test con muchos datos como para ser objetivos pero la experiencia de usuario es fluida). Simplemente comparto el link por si a alguno le interesa usar

I know this is not a revolution support forum, but as anyone noticed the following? I have a foreach loop to generate random samples. If I run the exact code below in normal r (2.14.1) it works as expected, but if I run it from revolution 4.2.0 each loop returns the same numbers. The only way I can get revolution to give different numbers is using 1 instead of 8 in registerDoSNOW(makeCluster(8,

Hola a todos, he encontrado una aplicación que se llama Revolution R, éste es su link: http://www.revolutionanalytics.com/why-revolution-r/benchmarks.php Presume de poder realizar procesamiento en paralelo. Me gustaría saber si eso es cierto, si merece la pena y si el procesamiento en paralelo se realiza de forma transparente al usuario o hay que programarlo. saludos, Fernando

I want to build R optimized, with either MKL, OpenBLAS or ATLAS.

Hello, I am trying to setup a private CRAN for work (behind a firewall). The best options available include miniCRAN <https://github.com/RevolutionAnalytics/miniCRAN>, drat <https://github.com/eddelbuettel/drat> and packrat <https://rstudio.github.io/packrat/>. One problem is these packages do not automatically generate the web pages that are on the CRAN. Examples:

Hi, all-- I've been working on a doParallel package to provide a foreach parallel backend for the new parallel package, but I am having trouble building the vignette.
