installr (version 0.8)

updateR: Checks for the latest R version, and if there is a newer version of R - downloads and installs it.

Description

This function performs the following steps:

• Check what is the latest R version. If the current installed R version is up-to-date, the function ends (and returns FALSE)
• If a newer version of R is available, the user is asked if to review the NEWS of the latest R version - in order to decide if to install the newest R or not.
• If the user wishes to - the function will download and install it. (you will need to press the "next" buttons on your own)
• Once the installation is done, you should press "any-key", and the function will proceed with copying all of your packages from your old (well, current) R installation, into your newer R installation.
• You can then erase all of the packages in your old R installation.
• After your packages are moved (and the old ones possibly erased), you will get the option to update all of your packages in the new version of R.
• You will be asked if to open the Rgui of your new R.
• Lastely - you can close the current session of your old R.
