R loop function over time

First off I'd like the apologize for any vague descriptions here. It's my first week on R and I am still getting used to the new lingo.

I am trying to show to movement of bike sharing stations over the course of a day on maps. I am using csv data from a website which refreshes every 60 seconds.

I would therefore like for my code to be running every minute which includes getting the data, making the map, printing and saving it.

How can I achieve that?

Thanks!
