install_version | R Documentation |
This function knows how to look in multiple CRAN-like package repositories, and in their
archive
directories, in order to find specific versions of the requested package.

package |
Name of the package to install. |
version |
Version of the package to install. Can either be a string giving the exact version required, or a specification in the same format as the parenthesized expressions used in package dependencies. One of the following formats:

dependencies |
logical indicating whether to also install
uninstalled packages which these packages depend on/link
to/import/suggest (and so on recursively).

Should package dependencies be upgraded? One of "default", "ask", "always", or "never". "default"

The repositories are searched in the order specified by the repos
argument. This enables
teams to maintain multiple in-house repositories with different policies - for instance, one repo
for development snapshots and one for official releases. A common setup would be to first search
the official release repo, then the dev snapshot repo, then a public CRAN mirror.
Older versions of packages on CRAN are usually only available in source form. If your requested
package contains compiled code, you will need to have an R development environment installed. You
can check if you do by running devtools::has_devel
(you need the devtools
package for this).
