Summary

This tutorial by Julien A covers the essentials of installing and loading R packages. It begins by explaining what packages are and their role in extending R’s functionality. The main focus is on installing packages from CRAN using install.packages() and from GitHub using devtools or remotes. The video also demonstrates using RStudio’s graphical interface for installation and loading. A key section emphasizes the ‘friendly method’ for sharing code, which involves using require() to check if a package is installed and installing it if necessary, thus avoiding inconvenience for collaborators. The tutorial also covers updating packages, both via RStudio and command line, and discusses handling package updates when a new major R version is released. The author provides practical tips for Unix systems, such as using parallel compilation. The video is aimed at R users, particularly students, and includes a brief mention of package removal from CRAN and how to install from archived sources.
