Returns the number of iterations used to produce of a collection of spatial interaction models

The function reports for each spatial interaction model of its sim_list parameter the number of iterations used to produce it (see sim_iterations())

Usage

grid_sim_iterations(sim, ...)

Arguments

sim

a collection of spatial interaction models, an object of class sim_list

...

additional parameters

Value

a vector of numbers of iteration, one per spatial interaction model

Details

Notice that sim_iterations() is generic and can be applied directly to sim_list objects. The current function is provided to be explicit in R code about what is a unique model and what is a collection of models (using function names that start with "grid_")

Examples

positions <- matrix(rnorm(15 * 2), ncol = 2)

  c(1, 2, 3),
