How to install and load a package in R language?

In R language, there are two functions that can be used to install and load a package.

1. Installation package: Use the install.packages() function to install packages. For example, to install the package named “ggplot2”, you can use the following code:

install.packages("ggplot2")

1. Load package: Use the library() function to load a package. For example, to load the recently installed “ggplot2” package, you can use the following code:

library(ggplot2)

This allows for installing and loading a package. If operating in RStudio, you can also directly install and load packages in the Packages panel.
