Greeting Listserv Readers, At http://r4stats.com/popularity I have added plots, data, and/or discussion of: 1. Scholarly impact of each package across the years 2. The number of subscribers to some of the listservs 3. How popular each package is among Google searches across the years 4. Survey results from a Rexer Analytics poll 5. Survey results from a KDnuggests poll 6. A rudimentary analysis

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.

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 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.

Hello, running windows vista, R2.9. Installed the following libraries: (*latticist*, *playwith* and *Cairo*) Wanted then to run, to evaluate the visualization features: >data(iris) >library(latticist) >latticist(iris) However, i tested my desktop and laptop and get the following error after typing latticist(iris): latticist(iris) Loading required package: playwith Loading

Greetings, I am pleased to announce the availability of the document, "R for SAS and SPSS Users", at http://oit.utk.edu/scc/RforSAS&SPSSusers.doc . It presents an introductory view of R for people who already know SAS and/or SPSS. Included are 27 programs written in all three languages (i.e. 81 total) so that people can see how R works compared to the other two, task by task. I

Dear R-helpers, I know of two ways to reading data within an R program, using textConnection and stdin (demo program below). I've Googled about and looked in several books for comparisons of the two approaches but haven't found anything. Are there any particular advantages or disadvantages to these two approaches? If you were teaching R beginners, which would you present? Thanks, Bob

Hi Folks, SAS Institute is adding official support for R: http://support.sas.com/rnd/app/studio/Rinterface2.html Cheers, Bob ========================================================= Bob Muenchen (pronounced Min'-chen), Manager, Research Computing Support U of TN Office of Information Technology Stokely Management Center, Suite 200 916 Volunteer Blvd., Knoxville, TN

Hi All, My paper "R for SAS and SPSS Users" received a bit more of a reaction than I expected. I posted the link (http://oit.utk.edu/scc/RforSAS&SPSSusers.pdf) about 12 days ago on R-help and the equivalent SAS and SPSS lists. Since then people have downloaded it 5,503 times and I've gotten lots of questions along the lines of, "Surely R can't do for free what [fill in

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

Hi All, I'm using the Hmisc summarize function and used list instead of llist to provide the by variables. It generated an error message. Is this a bug, or do I misunderstand how Hmisc works with lists? The program below demonstrates the error message. Thanks, Bob x<-1:8 group <- c(1,1,1,1,2,2,2,2) gender<- c(1,2,1,2,1,2,1,2) mydata<-data.frame(x,group,gender)

Hi everyone, is there a way/package in R that would allow me to select a group of points from a scatterplot by drawing a circle around them or some such? I can use 'identify' to pick individual points, but that gets tedious if one has more than 10-20 spots. I can easily select spots within a rectangle defined by picking points using identify... but a simple rectangle sometimes will

Hi All, We have all had to face skeptical colleagues asking if software made by volunteers could match the quality and accuracy of commercially written software. Thanks to the prompting of a recent R-help thread, I read, "R: Regulatory Compliance and Validation Issues, A Guidance Document for the Use of R in Regulated Clinical Trial Environments (http://www.r-project.org/doc/R-FDA.pdf).

Hello Rusers, I have worked on a R Wiki page for solutions in exporting R graphs, especially, the often-asked questions: - How can I export R graphs in vectorized format (EMF) for inclusion in MS Word or OpenOffice outside of Windows? - What is the best solution(s) for post-editing/annotating R graphs. The page is at: http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:export. I

Dear HelpeRs, I'm confused about the role of quotes around package names on the library and detach functions. Books on R use both approaches: library(Hmisc) describe(mydata) detach(package:Hmisc) and library("Hmisc") describe(mydata) detach("package:Hmisc") The help file for detach says "quoted or unquoted" and the help file for library says about the

Hi All, I searched around to find the number of R packages currently available, but didn't find anything, so I choose all repositories & told it to install. The list contained about 2,856 (correcting roughly for those installed). But the list includes repetitions such as 19 names that begin with "bvbovine". Selecting only CRAN and CRAN(extras) I get 1,344. Is there an easier

Hi All, I'm learning JGR 1.4-15 with R 2.4.1 in Windows XP (all patches applied). JGR looks great but I'm having trouble getting the data editor to save my results. I don't see anything in R-help about it. Here are the steps I followed: 1. I chose "Tools>Object Browser" & double-clicked on a data frame, "mydata". 2. A spreadsheet editor popped up and

Hi All, If I need to stack two data frames, I can use rbind, but it requires that all variables exist in both sets. I can make that happen, but other stat packages would figure out where the differences were, add the missing variables to each, set their values to missing and stack them. Is there a more automatic way to do that in R? Below is an example program. Thanks, Bob # Top data frame has

Dear R-Helpers, I was calling the TukeyHSD function and not getting confidence intervals or p-values. It turns out this was caused by missing data and the fact that I had previously turned on R Commander (Rcmdr). John Fox knew that Rcmdr sets na.action to na.exclude, which causes the problem. If you have this problem, you can either exit Rcmdr before calling TukeyHSD or you can set na.action to

Hello, I am trying to execute an example provided in the help files for the playwith() function. I try to execute the first example: library(playwith) if (interactive()) { options(device.ask.default = FALSE) ## Scatterplot (Lattice graphics). ## Labels are taken from rownames of data. ## Just click on the plot to identify points. playwith(xyplot(Income ~ log(Population / Area), data =
