PackagesAside from your own extensions of R via functions there are numerous packagesof functions that were contributed by others.A frivolous example: click on Packages on the tool bar of an R session and selectInstall Package(s). Select USA (WA) under the offered CRAN mirror sites.Under the offered packages list scroll down to sudoku and select it <strong>for</strong> installation.After it is installed you still need to invoke library(sudoku) on the command line<strong>for</strong> each new R session in order to have access to the sudoku functions.To see the functions available in this package look under sudoku in the packagessection of the web help initiated by help.start().
