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

Hi Do you know some articles, papers, something than tell about comparision between R and others softwares statisticals.

Dear Rusers, I have met a difficult problem on explaining the differences of principal component analysis(PCA) between R,S-PLUS and SAS/STATA/SPSS, which wasn't met before. Althought they have got the same eigenvalues, their coeffiecients were different. First, I list my results from R,S-PLUS and SAS/STATA/SPSS, and then show the original dataset, hoping sb. to try and explain it.

Dear folks ? I have a large (26 gig) ASCII flat file in fixed-width format with about 10 million observations of roughly 400 variables. (It is 51 years of Current Population Survey micro data from IPUMS, roughly half the fields for each record). The file was produced by automatic process in response to a data request of mine. The file is not accompanied by a human-readable file giving the

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.

Good day My name is Jos? Oscar, I'm from Mexico and I have some questions about foreign in your write.foreig( ) function. We know that this function generates the inputs to be able to run them or execute them in another program like SPSS, SAS or Stata. In these cases, when creating an example file, a matrix and using the function to execute the .sps file directly from SPSS, I don't care or

Alternate title: How can I persuade my students that R is for them? Alternate title: Can R replace SAS, SPSS or Stata for clinicians? I am teaching introductory statistics to twelve physicians and two veterinarians who have enrolled in a Mentored Clinical Research Training Program. My course is the first in a sequence of three. We (the instructors of this sequence) chose to teach R rather than

Dear all, I'm trying to rerun some data linkage exercises in R (they are designed to be done in SPSS, SAS or STATA) The exercise in question is to relabel the column "treat" to "1", if "yearsep" is smaller than 1988 and columns "proc1"-"proc3" contain the values 56.36 or 59.81. My pathetic solution to do this in R currently looks like

Estimados Hoy instale RStudio, y por sorpresa o desconocimiento de mi parte, veo que hay la posibilidad de importar datos excel, spss, sas, stata, texto, recuerdo consultas en la lista al respecto, posiblemente mucho se soluciones con las herramientas propuestas por RStudio.

Hello all, I hope I'm writing to the correct place. I believe that the R homepage will benefit from including the "description" meta tag in it's homepage. The reason is that google uses that tag to decide what to show when the R homepage shows up on a search result. The current description of the first result of searching "R" in google is: "*R*, also called GNU

Hi all, I've got a project where I have to calculate weight-for-age Z-scores, preferably using the WHO standards. WHO have been very nice to publish macros for doing this in both STATA,SPSS, SAS and Splus formats (see http://www.who.int/childgrowth/software/en/), but for some reason have chosen not to use the free R alternative to Splus. In the Splus zipfile there are nine datafiles with a

Dear all, I am trying to import a SAS file into R (in fact I only need the value labels from the formats file), using Hmisc package, but I get this error: my.sas <- sas.get("/home/adi/3", "fis1_sgg") sh: sas: not found Error in sas.get("/home/adi/3", "fis1_sgg") : SAS job failed with status 32512 I read some past discussions and I get the impression

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

>>> What were your biggest misconceptions or >>> stumbling blocks to getting up and running >>> with R? Easy. I terms of materials I have been unable to find good books that introduce users to R from the perspective of someone familiar only with packages like SPSS or STATA, or not familiar with statistics packages at all. Even introduction texts use jargon

I am trying to gain an understanding of R's capabilities in larger data set analysis. I really like R, but the datasets that I normally work with are in the 15m-50m range, sometimes much larger. The size owes to observations, not extraneous variables, so little can be done to "clean" the data of unnecessary elements. (i.e. database storage or external data manipulation doesn't

By any chance is any one aware of a website, book, paper, etc. or combinations of those sources that show plots of different distributions? After reading a pretty good whitepaper I became aware of the benefit of I the benefit of doing Q-Q plots and histograms to help assess a distribution.   The whitepaper is called: "Univariate Analysis and Normality Test Using SAS, Stata, and SPSS*" ,

Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean a rectangular structure such as a dataframe.) The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields) of the codebook may include: ? variable name ? type (character, factor, integer, etc) ? variable label

Does anybory knows any work comparing R with other (charged) statistical softwares (like Minitab, SPSS, SAS)? I work in a brasilian government bureau and I intend to use R as our preferable statistical software, but I have to show it's as good as the others. I also intend to use Weka, and for this one I have the same problem. Can anyone help me? Thanks René M. Raupp e-mail: rener@mpdft.gov.br

Hey everyone, I have again a loop question: After generating the dataset using Jan?s approach from my previous posting (http://r.789695.n4.nabble.com/Loop-over-several-variables-td4648112.html) I want to rename the Variables in the new dataset so that all y will be called tiy. Doing it separately the following line works fine: ti<-rename (ti,c(y5="tiy5")) So I thought I simply
