Update jstats to the latest version

jupdate() installs the most recent version of jstats. While jstats is in its pre-release phase this downloads and installs the latest pre-built version; once jstats reaches CRAN, the same command will update it the ordinary way. Either way, you run one command instead of having to remember an install line. It is safe to call from the console, a script, or a Quarto document.

Usage

jupdate(ask = FALSE)

Arguments

ask

Logical. When TRUE and the session is interactive, jupdate() shows the available and installed versions and asks for confirmation before installing. Defaults to FALSE (update without prompting), which is also what happens in any non-interactive session, such as a Quarto render.

Value

Invisibly NULL. Called for its side effect of installing the update, and for the messages it prints.

Details

The function checks for an internet connection first; if jstats is already up to date it says so and stops. The install runs in a separate R process so the copy of jstats loaded in your session does not lock its own files during the install (the usual cause of a failed update on Windows). After a successful update you restart R once to load the new version.

Examples

if (FALSE) { # \dontrun{
jupdate()            # update without prompting
jupdate(ask = TRUE)  # confirm before updating
} # }
