The number of cells that activates cell death in a species.
Details
This value is the minimum number of cells that enables cell death in a species. The cell of a species $S$ can die if and only if that $S$ has reached the death activation level at least once during the simulation.
Examples
# set the seed of the random number generator
set.seed(0)
# create a simulation
sim <- SpatialSimulation()
# get the simulation death activation level
sim$death_activation_level
#> [1] 1
# set the death activation level to 50
sim$death_activation_level <- 50
