MC-Simulation with foreach: Some cores finish early
Dear R-Users,
I run a MC-Simulation using the the packages "foreach" and "doMC" on a
PowerMac with 24 cores. There are roughly a hundred parametersets and I
parallelized the program in a way, that each core computes one of these
parametersets completely.
The problem ist, that some parametersets take a lot longer to compute than
others. After a while there are only a quarter of the cores still computing
(their first parameterset), while others ar...

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
