Installing packages without clicking

I need to install several (too many) packages from local *.zip
files.

Are you aware of being able to select multiple .zip files at one time
using SHIFT-click or CTRL-click?

is there any form to do it  without clicking?

I'm asking for a R code that allow me perform these task.

You could just do what the clicking does, i.e. call the function
install.packages() with appropriate parameters.  See
utils:::menuInstallLocal

Hope this helps,
