First, make sure that the R_LIBS_USER environment variable is set, that the
directory it specifies exists, and that the current user has write permissions
for it. Then, run:
Rscript -e "pkg <- readLines(\"<list>\"); install.packages(pkg, lib=\"${R_LIBS_USER}\", repo='https://cloud.r-project.org/')"<list> is a file containing a list of packages. The repo variable can also be
changed to the desired package mirror.
To update all packages from the CRAN repos, run:
update.packages()To update a specific package instead of all of them, run:
update.packages(oldPkgs=<list>)where <list> is either a string for a single package of list (c()) for more
than one.
To view any out-of-date packages, use:
old.packages()
