restorePackages: Restore Session Packages

In Sage-Bionetworks/sessionTools: Tools for saving, restoring and teleporting R sessions.

Description

Install packages that are missing from the local package library, but are described in the sessionInfo object. Future releases of this package will potentially allow the caller to specify package version options such as "latest", "referenced" for each package so that the each packge can be either upgraded to the latest version (if installed), or moved to the version referenced in the sessionInfo object, or left unchanged.

Currently, this function will only install a package if it is not already installed, and will always install the latest version available from the repository. If a package is already installed the installed version will be left intact.

Usage

restorePackages(sessionInfo, repos = getRepos(), warn = TRUE)

Arguments

sessionInfo	A sessionInfo object
repos	The repositories to search for packages
warn	Boolean indicating whether a warning be displayed if not all packages can be installed.

Value

This method is executed for it's side-effects, which is to install packages to the default library.
