R help - Oct 2008 - Running R at a specific time - alternative to Sys.sleep() ?

Dear R-Help,

Is it possible to set R up to run a particular script at specific
times of the day? trivial example: If the time is now 8:59:55am and I
wish to run a function at 9am, I do the following:


my.function <- function(x) {
    p1 <- proc.time()
    Sys.sleep(x)
    print('Hello R-Help!')
    proc.time() - p1
}
my.function (5)

[1] "Hello R-Help!"
   user  system elapsed
      0       0       5


What I would rather do is just put in the time at which I wish R to
execute at.

Hope that made sense, and thanks for any help in advance!
