[R] running functions at fixed times

I can only speak for the Linux/Unix enviroment:
mydata <- read.table(...)
to update mydata after a 60 second break.
An alternative is to use "cron" or "at". Both allow the specification
of exact execution times, while the "while" approach tries to imitate
a real time system.
Have a nice day
