[R] Show Progress in loop

[Rainer M. Krug]

Hi

I have a loop which is doing time consuming calculations and I would 
like to be able to have some feedback on where it is in it's 
calculations. I tried to simply show the counter variable in the loop, 
but id doesn't work as all display seems to be delayed until the loop is 
completed. Is there any way of displaying the progress of a loop?

The loop:

for (i in 2:Result$NoSims)
{
	ppp <- runifpoint(Result$NoPlants)
	K <- Kest(ppp)
	Result$LSim[i,] <- sqrt(K$iso / pi) - K$r
	CM <- (Result$LSim[i,] * Result$LSim[i,]) / abs(K$r[2] - K$r[1])
	Result$SigCM[i] <- sum(CM, na.rm=TRUE)
	i  #<========================Doesn't display in the loop
}
