Do you want to be doing other things with the R terminal in the meantime? Are you OK with the terminal being locked up between runs and just want to see the output updated?
Is it OK to have a new instance of R run the function? If the last one is doable then you can have your OS scheduled to run a script every 5 minutes and the script runs your function. How to do this depends on your OS, fairly easy with chron on linux and related OS's (you can see the updated file using the tail program, some versions will wait for new info to be appended and show it automatically). I have done this in windows before, but it takes several clicks and I need to rediscover the correct sequence each time. If you are happy with the 2nd set of conditions then you can just use a while loop to repeatedly run the function and include a call to Sys.sleep to wait the required time. Note that if your function takes more than a couple of seconds then you will want to reduce the amount of time accordingly. If the amount of time your function takes varies then you will not be running exactly every 5 minutes. If you need the 1st set of conditions, then you could load the tcltk2 package and use the tclTaskSchedule function. This is the most dangerous situation, you could end up with messed up data if you are trying to edit something at the same time the function runs and also tries to use/edit it. -- Gregory (Greg) L.
