Manage packages in RStudio

Use the Console

Open RStudio and ensure that the "Console" pane is active.

install.packages("package_name") # to install a package

update.packages() # to update all installed packages

remove.packages("package_name") # to remove a package

If you want to install multiple packages at once, you can use the c() function to create a vector of package names, and pass that vector to the install.packages() function. For example, to install the "ggplot2" and "dplyr" packages, you could run the following command:

install.packages(c("ggplot2", "dplyr"))

Once the installation is complete, you can load the package into your R session using the library() function. For example, to load the "ggplot2" package, you would run the following command:

library(ggplot2)

Note: If you are behind a proxy, you will need to configure your proxy settings in R before you can install packages. This can be done by running the following command:

Sys.setenv(http_proxy="http://proxy_host:proxy_port/")

Use the Packages pane

  • Click on the "Packages" tab in the lower right panel
  • Use the "Install" button to install new packages
  • Use the "Update" button to update packages that are already installed
  • Use the "Uninstall" button to remove packages that are no longer needed Screen Shot 2023-02-01 at 12 09 10 PM

Note: Always check the dependencies before uninstalling a package, as uninstalling a package may result in other packages that depend on it to stop working.

For more information, see the RStudio documentation.
