rig resolve

Resolve R versions. Checks the version number of an R version (e.g. release, devel, etc.), and looks up the URL of the installer for it, if an installer is available.

It prints the R version number, and after a space the URL of the installer. If no installer is available for this R version and the current platform, the URL is NA.

An R version can be specified in various ways:

• rig resolve devel is the latest available development version,
• rig resolve next is the next (patched, alpha, beta, etc.) version,
• rig resolve release is the latest release.
• rig resolve x.y.z is a specific version.
• rig resolve x.y is the latest release within the x.y minor branch.
• rig resolve oldrel/n is the latest release within the nth previous minor branch (oldrel is the same as oldrel/1).
