Subset of Given Time Points from sim_results Object

This function creates a subset of given time points from the sim_results object.

Usage

# S3 method for class 'sim_results'
subset(x, from = NULL, time_points = NULL, ...)

Arguments

x

sim_results object; returned by the sim function

from

numeric vector of length 1; indicates the starting time point from which all time point should be kept

time_points

numeric vector; indicates all time points to keep

...

further arguments to be passed to or from other methods

Value

sim_results object with only selected time_points present in the N_map slot

Details

Either from or time_points argument has to be specified. Time point passed by the from argument will be set as a cutoff point and all abundances for previous time points will be discarded.

Examples

if (FALSE) { # \dontrun{
# data preparation
library(terra)

n1_small <- rast(system.file("input_maps/n1_small.tif", package = "rangr"))
K_small <- rast(system.file("input_maps/K_small.tif", package = "rangr"))

sim_data <- initialise(
  n = n1_small,
  r = log(2),
  K_map = K_small,
  max_dist = 1000,
  rate = 1 / 1e3
)

sim_results <- sim(sim_data, time = 10)
summary(sim_results)

sim_results_cropped <- subset(sim_results, time_points = c(1:2))
