Welcome to r4stats.com. This site’s mission is to analyze the world of analytics, and to help people learn to use R. R is free, open source, analytic software that is similar to the “big three” commercial packages: SAS, SPSS and Stata.
Under Articles you’ll find an analysis of software popularity; a list of add-on products for SAS and SPSS as well as the R packages that do similar things; the many ways to call R from other software; and some tips about using Excel for data entry. Shorter commentary is listed under Blog. A extensive set of programs showing how to do the same tasks in R, SAS, SPSS and Stata are listed under Examples. You’ll find information about my books, R for SAS and SPSS Users and R for Stata Users under Books. My reviews of other books is listed under Miscellaneous. Finally, you can learn about the training I offer through Revolution Analytics under Workshops.
I welcome comments or suggestions regarding this site or analytics in general, so feel free to contact me at firstname.lastname@example.org or on Twitter, @BobMuenchen.
