This method return the rates of a species.
Examples
# set the seed of the random number generator
set.seed(0)
# create a simulation
sim <- SpatialSimulation()
sim$add_mutant(name = "A",
epigenetic_rates = c("+-" = 0.01, "-+" = 0.02),
growth_rates = c("+" = 0.2, "-" = 0.08),
death_rates = c("+" = 0.1, "-" = 0.01))
# Get the rates of "A-". In this case c("growth"=0.08, "death"=0.01,
# "switch"=0.02) is expected
sim$get_rates("A-")
#> $growth
#> [1] 0.08
#>
#> $death
#> [1] 0.01
#>
#> $switch
#> [1] 0.02
