You can install {updateme} from CRAN like so:

install.packages("updateme")

{updateme} modifies library() to tell you if your packages are up to date when you load them:

{updateme} works with packages installed from CRAN (and CRAN-like repos), Bioconductor, GitHub and GitLab. Packages installed from Bioconductor are intelligently checked against the version of Bioconductor you're using, and these get a special message if they're more recent than they probably should be:

The tidyverse is a special case, which gets its own modified startup message:

{updateme} is configurable using updateme_sources_set(). If, for example, you're using the development version of {lubridate} but you'd like to see which version is currently on CRAN, you can get this behaviour like so:

By default, {updateme} will check for new versions of a given package from wherever your version seems to have been installed from.

If you find you'd like to have {updateme} available all the time, consider loading it at startup by adding this snippet to your .Rprofile:

if (interactive()) {
  suppressMessages(require(updateme))
}

If necessary, you can turn {updateme} off using updateme_off(), and back on with updateme_on().

Some caching of downloads is used to make most calls to library() pretty quick. The cache resets every hour, but you can configure this using options():

# Set the cache expiry time to 30 minutes
options(updateme.cache_expiry = 30)
