Answer 1

You can use Sys.sleep(100) to stop execution for 100 seconds. It's a little inefficient vs. running some other process in the same instance and setting up a proper timer. But it's pretty easy.

Answer 2

An alternative to making your script loop: use an external job scheduling tool to call your script over the desired interval. If you have linux, I recommend checking out cron.
