How to Install and Include an R Package

We get a lot of questions about the usage of R libraries. The most common question is “can I use all the R libraries in your notebooks/consoles?”

Yes! You can use any of the libraries that have been published to the R package repository (CRAN).

Open up your notebook/console:

1. Install

install.packages("ggplot2") this will install the package if it hasn’t already been installed.

2. Include

library(ggplot2) this will call/include the library into your session.

3. Use

ggplot(data=iris,aes(x=Sepal.Length,y=Petal.Length))+geom_point()

Remember, when installing packages, you have to use quote marks inside the install.packages("") function but not when including them using the library().

Once libraries are installed, you don’t have to install them again. You can just call them with library() and then use them as you wish.
