Data Mining With R - learning with case studies

Here you may find important notices on the book and the use of its code.

New version of the book package (0.2.2) added to CRAN on 2012-02-23. You should update your package to this new version using the "update.packages()" function. You may want to check the release notes of this new version
New version of the book package (0.2.1) added to CRAN on 2011-04-14. You should update your package to this new version using the "update.packages()" function. You may want to check the release notes of this new version
An error in the code of Chapter 3 (pages 144 and 146) was found that leads to an execution error. The error can be easily corrected by changing the name of a function. See the section code errata for full details on the error and its correction. The code provided on this book web page in section "R Code" has this error already corrected so in case of doubts use this code.

Problem introduced by a recent version of quantmod

The book R package is strongly dependent on the excelent quantmod package. Unfortunately, a recent version of this package has introduced a small bug on the specifyModel() function that is used in the book (e.g. page 114). This bug was already solved by the package author (thanks Jeff!). The version with the correction is already available on CRAN. This is version 0.3-15. You should ensure that you have at least this version to avoid the bug. You can use update.packages() to update all your current packages to the newest versions. In case you are installing the quantmod package after 1/Dec/2010 you need not worry about this. In case of doubt on which version you have just load it doing library(quantmod), and then issue sessionInfo() and look at the results of this function that should show the version you have installed.

Portions of the code taking too long to run

Some of the code presented on the book may take some time to run, particularly on not so powerful computers. Here (section Extra Data Files of the top menu R Code) you can find a few Rdata files with the data structures created by theses parts of the code so that you can continue your replication of the case studies without having to run these computationally demanding parts.
