2. Packages in R

Before starting with packages in R, let us revise functions in R.

A package is a collection of R functions, data, and compiled code in a well-defined format. Packages are being stored in the directory called the library. R comes with a standard set of packages. You can see available packages by using the search() command.

Others are available for download and installation. Once installed, you need to load them into the session to use.

Below is an example of the running search() command:

[1] “.GlobalEnv” “tools:RGUI” “package:stats” “package:graphics”
[5] “package:grDevices” “package:utils” “package:datasets”
[9] “Autoloads” “package:base”

When you use the search() command you can see what packages are being loaded and are ready for use. For example, you will see graphics package that carries out routines to create graphs.

There are many packages that are being installed but not loaded by themselves. For example, splines package, that contains routines for smoothing curves, is being installed. But this splines package is not loaded by itself.
