If you need to install a package that is not available on the CRAN but on a github repository, you can do it using the "remotes" package. Indeed this package imports functions that will allow you to install a package available on github or bitbucket or gitlab directly on your computer.

To use the "remotes" packages, you must first install it:

install.packages("remotes")

Once "remotes" is installed, you will be able to install all R package from github or from their URL.

For example, if you want to install the last version of a "gganimate", which allow you to animate ggplot2 graphes, you can use :

remotes::install_github("thomasp85/gganimate")

By default the latest version of the package is installed, if you want a given version you can specify it :

remotes::install_github("thomasp85/gganimate@v1.0.7")

You can find more information in the documentation of remotes : https://remotes.r-lib.org
