My advice would be to avoid the network in one of the following ways 1. Store installed packages on your local drive 2. Copy the installed packages to a tempdir on your local drive each time the script is executed 3. Keep an R session running in perpetuity and source the scripts within that everlasting session 4. Rewrite your scripts to use base R only.
I suspect this solution list is exhaustive.
