Extract all the destination flows from a collection of spatial interaction models

The function extract destination flows from all the spatial interaction models of the collection and returns then in a matrix in which each row corresponds to a model and each column to a destination location.

Usage

grid_destination_flow(sim_list, ...)

Arguments

sim_list

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

...

additional parameters of the destination_flow() function

Value

a matrix of destination flows at the destination locations

Examples

positions <- matrix(rnorm(15 * 2), ncol = 2)
distances <- as.matrix(dist(positions))
production <- rep(1, 15)
attractiveness <- rep(1, 15)
all_flows <- grid_blvim(distances,
  production,
  c(1.1, 1.25, 1.5),
  c(1, 2, 3),
  attractiveness,
  epsilon = 0.1
)
g_df <- grid_destination_flow(all_flows)
## should be 9 rows (3 times 3 parameter pairs) and 15 columns (15 destination
## sites)
dim(g_df)
#> [1]  9 15
