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

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

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

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 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 - I've scoured the mailing list archives as well as other help sources online and haven't figured out what my problem is or what I'm doing wrong. Any help would be greatly appreciated. Scenario: I have a samba 3.5.5 server running on CentOS 5.5. This system is a member of an Active Directory domain. FYI, I am not the domain administrator, but I am an OU admin and can create

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)

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

With SAS I mean the SAS System Version 9.4 and SAS > Enterprise Miner. I don't expect a complete list, just two or three

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).

Dear R-Helpers, Why does R show character missing values in vectors as NA and when stored in a data frame as <NA>? I've searched but did not find an explanation. Thanks, Bob > gender <- c("f","f","f",NA,"m","m","m","m") > gender [1] "f" "f" "f" NA "m" "m"

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

Hi All, A few weeks ago I suggested that it would be nice to be able to submit lines from the help files for execution. You can cut and paste them into the console, or enter example(function) to run them all. However, I often find myself wanting to run just a line or two, or even parts of a line to see an intermediate result. It turns out that this is one of the many nice features of the JGR

Hi All, I'm stumped on something that must be trivial. I created a correlation matrix on 4 variables (6 correlations) using Hmisc's rcorr function. I wanted to correct the P-value matrix for the number of tests done, so I ran it through the p.adjust function. That function adjusted for the 12 p-values it saw, rather than 6. I added the argument n=6 to p.adjust but it requires that n be

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

Dear R-Helpers, I've looked high and low for a function that provides frequencies, proportions and cumulative proportions side-by-side. Below is the table I need. Is there a function that already does it?

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
