Examples

distances <- french_cities_distances[1:10, 1:10] / 1000 ## convert to km
production <- rep(1, 10)
attractiveness <- log(french_cities$area[1:10])
all_flows <- grid_blvim(
  distances, production, c(1.1, 1.25, 1.5),
  c(1, 2, 3, 4) / 500, attractiveness,
  epsilon = 0.1
)
g_df <- grid_destination_flow(all_flows)
## should be 12 rows (3 times 4 parameter pairs) and 10 columns (10
## destination locations)
dim(g_df)
