For what I understand you run this every time you use R on a Tuesday, which is not what I would want.

I edited Rprofile to update everything on Tuesdays. I've been doing this since 2.0 and I think I've had R running almost every Tuesday, which begs the question of what I would be doing if R hadn't come into existence.
In any case, It works pretty well:
## This script gets all the packages I don't already have # Run this once a week - say Tuesdays if (interactive() ) { library(utils)} is.tuesday <- as.POSIXlt(Sys.time())$wday == 2 if (is.tuesday == T) { cat("Running a package check...\nOccurs once a week, on Tuesdays\n") cat("Upgrade existing packages and check for new packages (y/N)? ") check.new <- as.character(readLines(n = 1)) if (any(check.new == "y", check.new == "Y")) { options(CRAN = "http://cran.us.r-project.org/";) cat("This can take a few seconds...\n") x <- packageStatus(repositories = getOption("repositories")()[[1]]) print(x) install.packages(x$avail$Package[x$avail$Status == "not installed"]) cat("Upgrading to new versions if available\n") upgrade(x) } }

Is there a way to set a cron job to automatically update packages? Maybe something like this:
$unixprompt> R --vanilla update.packages()
If you put update.packages(repos="http://cran.us.r-project.org";, ask=FALSE)
in a file update.R you can do R CMD BATCH update.R update.log or even fancier, something like R CMD BATCH update.R update-`date --iso-8601`.log
to keep dated log files.
