I'm running R 2.14.0 on my Mac - downloaded/installed ggplot2 package which is used in this book. Tried to install gcookbook to get the data sets for many of the examples in the book. (See "Software and Platform Notes")
But this is what happens:
In getDependencies(pkgs, dependencies, available, lib) :
package ‘gcookbook’ is not available (for R version 2.14.0)
Hi Henry - I believe this is because CRAN doesn't automatically build binary versions of new packages for previous versions of R. Since gcookbook was only recently added to CRAN, I think it's only built for R version 2.15.2.
You may be able to install it as a source package by running install.packages("gcookbook", type="source"). Another option, which I recommend, is to download and install the latest version of R.
