This works well as now I can leave it running in the background without having it flash up or resetting window sizes. Thank you.

Also, for an async solution, try something along these lines

library(tcltk)
f <- function() barplot(rpois(4, lambda=3)) g <- function() {f(); if (run) tcl("after", 4000, g)} # reschedule after 4000 ms run <- TRUE; g()

To stop it:

run <- FALSE

(With this structure, the time to run f() is added into the interval between invocations. For tighter timing control, reschedule before running f(), but then you'd better be sure it completes in time for the next iteration.)
