similar to: (New) Popularity of R, SAS, SPSS, Stata...

Dear R-Helpers, SAS Institute just mailed out the notice below regarding a survey of people who do data mining. To help keep the survey from becoming biased toward commercial software, I thought it would be good to post it here as well. Cheers, Bob Fourth Annual Data Miner Survey Rexer Analytics has asked statistical and data mining software vendors to forward this survey as a courtesy. (SAS is

Greetings, I've just put out the latest version of "The Popularity of Data Analysis Software" at http://r4stats.com/popularity. This update includes complete data for 2010, the addition of number of blogs for each software, more coverage of Statistica, and, where possible, measures regarding the implementations of the SAS Language: Carolina and the World Programming System (WPS).

Hi All, I've been fiddling around with various ways to estimate the popularity of R, SAS, SPSS, Stata, JMP, Minitab, Statistica, Systat, BMDP, S-PLUS, R-PLUS and Revolution R. It's not an easy task. You can see what I've come up with so far at http://r4stats.com/popularity . I'm sure people will have plenty of ideas on how to improve this, so please let me know what you think.

Hi Everyone, I'm writing to announce a new conference: Predictive Analytics World, Feb 18-19, 2009 in San Francisco (www.predictiveanalyticsworld.com). The goal of Predictive Analytics World is to serve as the go-to event, covering today's commercial deployment of predictive analytics, across industries and across software vendors. In a nutshell, PAW is a warehouse of case studies. And

Hi everyone, Predictive Analytics World's program for Feb 18-19 in San Francisco (www.predictiveanalyticsworld.com) has grown a bit since my post several weeks ago, and is looking better than ever. The conference covers today's commercial deployment of predictive analytics, across industries and across software vendors. In a nutshell, PAW is a warehouse of case studies. In breaking

I write about R every weekday 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 March: The doSMP package, which enables parallel processing for R on multiprocessor machine, is now available on

Hi All, I now have programming examples for common research tasks done in R, SAS, SPSS and Stata at http://r4stats.com. The examples fall into the following categories: Data Import & Export Data Management Enhancing Output Graphics, ggplot2 Graphics, Traditional Selecting Variables and Observations Statistics For the graphics examples, I got lazy and only show the R code done two ways.

Hi All, I have substantially expanded the table that compares SAS and SPSS add-on modules to somewhat equivalent R packages. This new version is at: http://r4stats.com/add-on-modules and I would very much appreciate any feedback you might have on it. The site http://r4stats.com is the replacement to http://RforSASandSPSSusers.com and includes the support files for both "R for SAS and SPSS

Hello all, I've developed a prototype package called PopCon (short for popularity contest), a package for tracking the popularity of R and its packages. I'd like this work to be similar in spirit to the Debian package popularity-contest: http://popcon.debian.org/. Once Popcon is loaded, it captures two kinds of information from the user and stores it into a cache: the names of the

¿Donde se encuentra R dentro de la informática? Hoy de casualidad y por otro tema vi un gráfico que podría emplicar esa pregunta. http://langpop.corger.nl/ Javier Marcuzzi

I am needing to create a new identifier variable for a data set which has no ID variable in the original file. I am basically wanting to take the count of each row and add "sd" in front of it - so it would look like so sd1 sd2 sd3 sd4 sd5 etc....... I have no idea how to do this. I am a SAS user trying to learn R. This question may have been answered previously, but I could be

I'm an SPSS user trying to make the transition to R. Can someone help me translate the following SPSS code into R?: GLM Total_tp1 Total_tp2 WITH Age Sex   /WSFACTOR=Time 2 Repeated   /METHOD=SSTYPE(3)   /CRITERIA=ALPHA(.05)   /WSDESIGN= Time   /DESIGN= Age Sex Age*Sex. Also. can anyone recommend any resources to help SPSS users learn to things in R? Thanks, -kristi [[alternative HTML

There are loads of resources for users of any other statistics package who are learning R. For example http://www.google.com/search?q="r+for+sas-users" The reverse isn't the case http://www.google.com/search?q="sas+for+r-users" Having heard rumors of how unelegant other statistics packages are, I don't see why any R-user would ever want to switch to anything else.

Dear all, I am a stata user and I am moving my first steps in R. I am dealing with a silly issue concerning looping over variables. I read previous posts on similar topics in the R help archive, but I did not find a solution. Here is my case: I run a simple bivariate linear regression saving the output in objects called: pd.memb.0, pd.memb.1, pd.memb.2, pd.memb.3 pd.memb.0 <- lm(E.fs.memb ~

How difficult is it to get a good feel for the internals of R, if you want to learn the general code base, but also the CPU intensive stuff ( much of it in C or Fortran?) and the ways in which the general code and the CPU intensive stuff is connected together? R has a very large audience, but my understanding is that only a small group have a good understanding of the internals (and some of those

Hi I'm implementing (for the open source) a little voip app. (intended to be used by another remote-assistance tool, but usable 'per se'). I'm currently using GSM encoder, but would like to use Speex, too. I must make some mistake using the lib, because when using Speex I have some problems with speech quality (no matter how I tune Speex params.). I'm asking if it's
