The %v is automatically expanded to the major and minor version of R, so with R 3.5.1 this path becomes ~/R/library/3.5. You can also alternatively set R_LIBS_USER to a different path but make sure to include the %v wildcard. R_LIBS_USER is actually set by default to this scheme, (to ~/R/win-library/x.y on Windows and ~/Library/R/x.y/library on macOS) but the directory may not already exist, so one option is just to create this directory ( fs::dir_create(Sys.getenv('R_LIBS_USER'))). You also want to make sure the package library is specific to the minor version of R. Installing and Using R Packages Install a package from CRAN Install a package from Bioconductor Install a package from Github View the list of installed. This makes it easy to re-install R if needed without touching your CRAN packages. I suggest you keep the packages R comes with (base and recommended) packages separate from the rest of your packages. While it may work some (even most) of the time, R-core does not guarantee compatibility between these versions and things could break (even break silently). Install and load a package called installr, using these commands: R Install the installr package install. # Installr includes a package migration tool but this simply copies packages, it does not update themĬ may see some suggestions that you can just copy your packages even when the ‘minor’ version changes. This calls package names and installs them from repos, thus all packages should be correct to the most recent versionįor ( p in setdiff( packages, installed.packages())) # Install library - run in the new version of R.

Install.R() # download and run the latest R installer If( !require( installr)) #load / install+load installrĬ() # tells you if there is a new version of R or not.

# Run in the old version of R (or via RStudio)
