Welcome to r4stats.com. This site’s mission is twofold: to analyze the world of data science, and to help people learn to use R. R is free, open source, software for data science that is similar to the “big three” commercial packages: SAS, SPSS, and Stata.
In the menus above under Articles you’ll find an analysis of data science 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 a few other articles. 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 have offered in partnership with the American Statistical Association, DataCamp.com, RStudio, New Horizons Computer Learning Centers, and Xerox Learning Services under Workshops.
I welcome comments or suggestions regarding this site or data science in general, so feel free to contact me at firstname.lastname@example.org or on Twitter, @BobMuenchen.
