An Exellent Text of Introductory Statistics for R Users


Finally, Verzani (2004) presets is a book for students who want to self-learn R. This book is written in clear description of concepts, thoughtful organization of chapters, and nicely formatted R codes. Compared to the text books by Dalgard (2001) and Fox (2002), this book is the best.

Using R in introductory statistics classes

我在2004年有機會到U of Michigan, Ann Arbor的ICPSR方法營親近John Fox與Robert Andersen兩位老師,對於他們投注在R的教學印象深刻。他們最近所合寫中的這一篇文章,很值得有興趣將R導入政治學研究方法的老師們參考:

comparison of statistical packages

Michael Mitchell, UCLA ATS Statistical Consulting Group, provided a comprehensive comparison of SPSS, STATA, and SAS. Check out his report here.

On p.31, he talked about R and thinks that R is very difficult to learn. Well, I agree it is difficult to learn R if there is no right road map and guidence. But, R is not difficult to master if you just want some results. Most of time, R requires only several lines to get the results. Therefore, it is still an open for students to decide what they like. If I like Stata, I would say that a graphical user interface of R (R-GUI), such as JGR will make R look and and easy to use as Stata.

a comparison of text editors for R

While I am evaluating Jedit as a text editor for beginners of R, I found this site that introduces JGR and SciViews, the two GUI packages that be attractive to R users.
