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 ...
