using R
You need to get the primer for R and install the R package; other material is optional. Instructions are given below.
Text downloads (.pdf files)
- Get the R primer that shows how to use R to do the computations discussed in the book.
- Get RSscripts.zip, a collections of scripts for use with R that reproduce most of the computations shown in the book.
- Documentation for the functions in the alr3 package is included with the package, but you can download the function documentation separately.
- Documentation for data sets is also included with the alr3 package, but you can download the data set documentation separately.
The alr3 package for R
If you are running R, connected to the internet, and have write privileges on your computer's disk, you can install alr3 by typing the following command into the R command window:
> install.packages("alr3")
You may be prompted to select a location for the download; pick a site close to your home. After this, the package should install itself. You do not need to install again unless you install a newer version of R.
If you don't meet the criteria of the last paragraph, you can go to the page for your computer type:
To use the alr3 package, start R. If the package is in the standard location, type
> library(alr3)
If the package is somewhere else, you will need to provide the complete path to the package directory, for example on Windows, you might type
library(alr3,lib.loc="E:\Rlibraries"),
if you have created the package directory on a removable "E" drive.
To use a data file like forbes.txt with R, type
> data(forbes)
R resources
From
www.r-project.org, the home for R, you
can get a wealth of information about R, including books and
other documentation, access to CRAN (pronounced "see-ran"), which
includes the program and many add-on packages, and other
interesting stuff. The help files available from the Help menu of
the program can also be useful.
