Show Progress in loop
...39;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
}

Vectorizing loop
Hi
I have the following loop and would like to vectorize it. Any ideas if
it is possible?
Thanks,
Rainer
Tha 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)
print(i)
flush.console()

Calculating mean together with split
Hi
I have a table called npl containing results of simulations.
It contains about 19000 entries and the structure looks like this:
NoPlants sim run year DensPlants
1 6 lng_cs99_renosterbos 1 4 0.00192
.
.
.
it has 43 different entries for sim and year goes from 1 to 100, and run
from 1 to 5.
I would like to calculate the mean of DensPlants for each simulation and
each year seperately, i.e. calculat...
