Building subforests

This method builds a subforest using as leaves some of the original samples.

Arguments

sample_names

The names of the samples whose cells will be used as leaves of the new forest

Value

A samples forest built on the samples mentioned in sample_names

Examples

# set the seed of the random number generator
set.seed(0)

# create a simulation
sim <- SpatialSimulation()
sim$add_mutant(name = "A",
               growth_rate = 0.2,
               death_rate = 0.01)
sim$place_cell("A", 500, 500)

sim$death_activation_level <- 100
sim$run_up_to_size(species = "A", num_of_cells = 50000)
