Sounds like Homebrew to me.  If so, or anyway, create a file (before
updating) which contains something like

	 #!/usr/bin/env Rscript --vanilla
	 # set the Mirror
		r <- getOption("repos")
		 r["CRAN"] <- "https://cloud.r-project.org/"
		options(repos = r)
	 ), dependencies = TRUE)

or similar and run it if the additional libraries disappear.

You can fill this with something like

	 grep -h library *R \
	 |awk -F 'library' '{print $2}' \
	 |sed 's/(//g;s/)//g' \
	 |sort -u \
	 |awk '{print "\"" $1 "\","}'
	 |sed '$ s/,$//'

or in a few lines of the language of your choice generate the whole
script. And of course refine to your liking with something like

	 find ~/R -name '*.R' -exec grep -h library {} ';' \

greetings, el

To email me replace 'nospam' with 'el'
