From the reviews of the third edition: "Written to coincide with Version 7.0 of S-PLUS, the fourth edition of The Basics of S-PLUS furnishes a gently paced, but detailed, introduction to the S-PLUS statistical computing environment." Journal of Statistical Software, Vol. 14, December 2005 "Now in its fourth edition, this paperback continues to evolve smoothly, keeping ... Read moreup with changes in S-PLUS and its underlying language, S...If you own a first or second edition of this book, I recommend updating to the fourth edition." Journal of the American Statistical Association, September 2006 "This is the third edition of the book within five years of publication. This gives an idea of the popularity of the book. The basic structure of the book remains the same. But the new edition covers the S-Plus version 6 for Unix and Windows. In particular the contents now reflect introduction of a graphical user interface (GUI), new formats of graphics and for export and import of data. The comparable public domain software R receives a separate coverage as an introduction to R.” (Arup Bose, Sankhya, Vol 64 (3), 2002) "This is an introductory book on S-PLUS that even first-time users will find accessible, informative, and easy to follow. … One strength of the book is its coverage of several implementations of S-PLUS, in particular of its graphical user interfaces (GUIs) under both Windows and UNIX. … All the while, the book avoids the overwhelming complexities typical of a software manual, and the few, well-thought-out exercises (with careful solutions) at the end of each chapter supply the motivation to explore more advanced topics." (Mario Peruggia, Journal of the American Statistical Association, December, 2002) "The second edition (2E) was 50% larger than the first edition. This update has considerably fewer changes. … Its inclusion of GUI coverage makes it a good choice for any statistician who wants toget started with S-PLUS." (Technometrics, Vol. 45 (2), May, 2003) From the reviews of the fourth edition: "A basic introduction to S-Plus statistical computing based on version 7.0 of S-Plus. It is suitable for people with little computing knowledge and basic understanding of statistical data analysis. … Overall presentation in this book is good and this book is ideal for a quick basic introduction to S-Plus. It is well suited for self-study and may be considered as a text book for S-Plus statistical computing. If the reader carefully goes through this book, he will acquire substantial knowledge in S-Plus data analysis." (Anil K. Ghosh, Sankhya: The Indian Journal of Statistics, Vol. 68 (1), 2006) Show Less
