SAS and R: Data Management, Statistical Analysis, and Graphics 1st Edition
An All-in-One Resource for Using SAS and R to Carry out Common Tasks
Provides a path between languages that is easier than reading complete documentation
SAS and R: Data Management, Statistical Analysis, and Graphics presents an easy way to learn how to perform an analytical task in both SAS and R, without having to navigate through the extensive, idiosyncratic, and sometimes unwieldy software documentation. The book covers many common tasks, such as data management, descriptive summaries, inferential procedures, regression analysis, and the creation of graphics, along with more complex applications.
Takes an innovative, easy-to-understand, dictionary-like approach
Through the extensive indexing, cross-referencing, and worked examples in this text, users can directly find and implement the material they need. The book enables easier mobility between the two systems: SAS users can look up tasks in the SAS index and then find the associated R code while R users can benefit from the R index in a similar manner. Demonstrating the code in action and facilitating exploration, the authors present extensive example analyses that employ a single data set from the HELP study. They offer the data sets and code for download on the book’s website.

About the authors

I'm a biostatistician and an Associate Professor in the Department of Population Medicine at the Harvard Pilgrim Health Care Institute and Harvard Pilgrim Health Care. There, I work on research projects ranging from observational epidemiology to public health surveillance to delivery science. I've been a SAS user since 1990 and an S+/R user since 1996. Most of my current work outside research has been devoted to helping people learn SAS and R, the two dominant statistical computing tools in the medical area today. While many users are wholly invested in just one of these environments, I encourage people to be stronger analysts by maintaining capabilities in each. Having access to more tools means a greater likelihood of having access to the right tool.
At home, I live in beautiful western Massachusetts with my wife, Alice, and Facha the dog. Oops, that must have been a flashback-- I mean, with Sara, Abby and Sam, and Pepper the cat.

Nicholas Horton is a Professor of Statistics at Amherst College. He earned his ScD in Biostatistics from the Harvard School of Public Health. Nick is interested in developing methodology for the analysis of missing and/or incomplete data, the development of methods for analyzing multiple informant and multiple outcome data in services research, alcohol and drug abuse studies, as well as statistical education. He is enthusiastic about creating and improving rail-trails, and is the co-founder and President of the Friends of Northampton Trails and Greenways (http://www.fntg.net).

"SAS and R" is a well-crafted dictionary of how to do things in both SAS and R. For each topic the authors clearly and concisely show how to perform that task in SAS, then in R. They typically provide a paragraph of description for each. The brevity of explanation allows the authors to cover a wider range of topics. If you needed to know more about a topic, at least they have given you a good start and you'll know what SAS statements or R functions to pursue. That's helpful information, especially in R. Each chapter concludes with example programs with output which demonstrate the topics covered. Output for both packages is shown. The book does include brief introductions to both SAS and R in the appendices but, as the authors state in the preface, their book is not meant to be read cover to cover. However, unlike a standard dictionary, the entries are organized by category, so reading several entries in a row is usually helpful.
"R for SAS and SPSS Users" is a step-by-step introductory text, meant to be read in order. I assume you already know SAS or SPSS, and the only discussion of them is used to help you learn R. Rather than a paragraph of explanation per topic, I typically provide several pages, stepping through complete example programs, and pointing out where beginners typically make mistakes (often caused by expecting R to work more like SAS or SPSS). However, given that added explanation, the range of topics is narrower. I do include programs in all three at the end of each topic, but I provide detailed explanations for only the R programs. To save space, I show only the R output. While I include some redundancy to facilitate using it as a reference, it is important to read it through at least once.
So for someone learning R, these books complement each other well. I recommend starting with "R for SAS and SPSS Users" to build a solid understanding of R, then use "SAS and R" to look up any additional topics.
For someone learning SAS, I recommend reading a book devoted to that topic, such as, "The Little SAS Book: A Primer", then using "SAS and R" to look up the many topics that book does not cover. "R for SAS and SPSS Users" is not a good choice for learning SAS or SPSS.
In either case, you'll probably need additional books devoted to the particular methods of analysis you need.
Much shorter than most of the books I have seen on R, but it can start with the assumption that you know how to do things in general and just want to see how to do them in a new system.
I know SAS and statistical methods well. And I can manipulate data if I'm in the mood. But, the time has come to add R to my skills and I wanted something that might make things easier. So, I saw the stellar reviews for this book and decided to give it a try.
What I discovered is that the concept doesn't work for me. Since I know the methods well, I don't need to refer to how to do something in SAS in order to understand how to do it in R. Things get further complicated because there are often many ways to do something in SAS, so for someone well-versed in SAS going to R, again what matters is the particular task, not any particular way of accomplishing it in SAS.
Let me try an analogy. I think of SAS and R as languages. I speak SAS but want to become a *native* speaker of R. That means I have to learn to think in R rather than by attempt a work-for-word translation from SAS. The word-for-word translation might work for closely related languages (the statistical analysis portions of SAS and SPSS, for example [or maybe even Stata and R?]), but not for two so different as SAS and R. In computer language terms it's like translating Fortran into APL.
I can see how this approach might work for someone who is on the same footing in both R and SAS as a way to compare and contrast, but as a way for going from one to the other, what works best for me is starting with a clean slate.
