similar to: SAS for R-users

Hi List, I had the pleasure of taking Dr Bob Muenchen's interview for his upcoming book R For SAS and SPSS users. He has spent 27 years in this field while I have spent almost that much on earth. So this is more like a fan blog interview. I thought it would be of use to people curious about R, or even SAS , or SPSS if they have not worked on either of these packages before. Having fought my

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 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

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

All I have been looking into the books on performing statistics in R, in particular I am interested in General Linear Mixed Models, for Randomized Complete Block Design Experiments The list I have come away with so far is: Mixed Effects Models in S and S-plus by Pinheiro (2002)

Cordial saludo Estoy realizando un análisis con datos categóricos, donde tengo una tabla 3*3, son tres métodos de estudio comparado con tres niveles de asimilación del problema, lo ideal seria poder decidirse por algún método de estudio en especial, lo único que he encontrado es el test para independencia chi-cuadrado, pero no he podido encontrar algo que me sugiera por un método u otro, me

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.

I was only trying to say that it shouldn't be very difficult to find these for/do loops which are interesting from the parallelization perspective (in general, not all for/do loops can be reconstructed). As for the dependence analysis, I need this piece for my project, and I am

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

Can someone please recommend to me a book on the programming language that R is based on? I'm looking for a foundational book that teaches the logic of the S language. It seems that knowing the underpinnings of the language can only make using R a bit easier. Any leads are greatly appreciated . . . Matt. [[alternative HTML version deleted]]

Hi folks, I have a dataset from a trial measuring the subjects' pupils. There are many measurements, all of which must be analysed in a similar fashion; so if I get the analysis right for one of them, I've got them all. For simplicity, let us call any measurement we may be interested as "response". The study design is an unbalanced latin square, with 5 periods, 5 treatments and

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

Greetings, I'm learning R and I'm stuck on a basic concept: how to specify a logical condition once and then perform multiple transformations under that condition. The program below is simplified to demonstrate the goal. Its results are exactly what I want, but I would like to check the logical state of gender only once and create both (or any number of) scores at once.

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).

I realize this is a CentOS mailing list but because it is based directly on RHEL, I would assume there are a few individuals who frequent the list that have passed the RHCE exam. I plan on taking the exam this March and was wondering if there are any tips you RHCEs out there could provide that may help me. Thanks!

Hi all R gurus out there, Im a kind of newbie to kalman-filters after some research I have found that the dlm package is the easiest to start with. So be patient if some of my questions are too basic. I would like to set up a beta estimation between an asset and a market index using a kalman-filter. Much littarture says it gives superior estimates compared to OLS estimates. So I would like to

Dear R People: Could someone recommend a "baby book" on path analysis and SEM, please? Or if someone has an example that they use in the classroom setting, that would be very cool too.

Dear R-Helpers, I suspect I'm about to ask a FAQ, but I haven't been able to find an answer in the FAQ, AItR or an R Site Search. When I look at the methods of summary (below) it says, "Non-visible functions are asterisked". I looked at the help file for summary.princomp, which did not comment on it being non-visible. I ran its help file example, which printed visible output. I

bRotheRs & sisteRs, I am once again attempting to learn enough Latex voodoo to get something done, and failing comically. The document "RJAuthorguide.pdf" mentions that one can get page width figures through the use of the "figure*" or "table* environments, but despite considerable searching through the mail archives and reading Frank Harrell's discussion of
