Packages

R can be extended by more than 11'000 Packages. The standard (or base) packages are considered part of the R source code. They contain the basic functions that allow R to work, and the datasets and standard statistical and graphical functions that are described in the R manual.

Using a Base Packages

Let us assume you want to do some simple statistics about the height and weight of a family of four. The familly consists of the parents Jane and Joe and their kids Jim and June.

Joe

Jim

June

52

Now let us see what R can do with that values.

Using an additional Package

Since we provide only the basic R package, sooner or later you want to extend it with additional packages. This can be done by creating a local package library and install the additional packages there.

Configure R to use your local package library

Let us assume that you would like to create a local package library in ~/R/libraries. The following commands create that library and configure R to always use it as a resource.

Installing the rJava package

An Example Usage with rJava

Let us assume you have created a simple Java Class which creates a number of variables to be used and manipulated by R. Below you find the steps to use that class from within R.
