install.packages(c("dplyr", "tidyr", "stringr"))
This will download and install the latest versions of dplyr, tidyr, and stringr from CRAN. You can also specify a repository other than CRAN by using the repos argument in the install.packages() function. For example, if you want to install or update the package devtools, which is a package that helps you create and manage your own R packages, from GitHub, you can run the following command in R:
install.packages("devtools", repos = "
This will download and install the latest version of devtools from GitHub.
Use the update.packages() function to check and update all installed packages
To check and update all installed packages in your R library, you can use the update.packages() function in R. This function will compare the versions of your installed packages with the versions available on CRAN and other repositories and prompt you to update any outdated packages. For example, if you run the following command in R:
update.packages()
This will check all installed packages in your R library and ask you whether you want to update any outdated packages. You can choose to update all packages by typing "a", update none by typing "n", or update some by typing their numbers separated by spaces. You can also use the ask argument in the update.packages() function to specify whether you want to be asked or not. For example, if you run the following command in R:
update.packages(ask = FALSE)
This will update all outdated packages in your R library without asking you for confirmation.
Use the library() function to load and attach packages to your R session
