[R] pause

[ben@zoo.ufl.edu]

  I don't know how the timing would work exactly, but you could write a
very short piece of C code (details would depend on your operating system,
man usleep for Linux) -- you'd probably have to calibrate for the average
time that the function call took, too.
  Or you could just try to calibrate a delay loop:

delayloop <- function(x=1000) {
  for (i in 1:x) {}
}

dtime <-
sapply(seq(3,6,by=0.2),
  function(z)system.time(delayloop(10^z))[3])

plot(seq(3,6,by=0.2),dtime,type="b",log="y")

of course, this would vary from system to system depending on speed ...
