The ggplot2 library

Lets take a look at the following steps to install the ggplot2 library:

1. Open the R console or terminal and then type the following command:

      install.packages("ggplot2")

The preceding command line will then ask you to select a server as follows:

      install.packages("ggplot2")
      --- Please select a CRAN mirror for use in this session ---

1. It will now install ggplot2 and its dependent libraries. If you want to avoid selecting a mirror server, then you can specify the mirror server within the install.packages() function using repos=.
