Examples

library(roroph)
library(dplyr)

# Load the network data
data(roro_routes)

# Example 1: Basic Analysis of Connectivity
# Calculate the average passenger capacity per highway system
roro_routes %>%
  group_by(highway_type) %>%
  summarise(mean_pax = mean(pax_cap, na.rm = TRUE))

# Example 2: Spatial Adjacency Logic (Anselin/LeSage framework)
# Filter for the Western Nautical Highway (WNH) hubs
wnh_hubs <- roro_routes[roro_routes$highway_type == "Western", ]

# Simple validation check of coordinates for spatial weight construction
if (requireNamespace("sf", quietly = TRUE)) {
  library(sf)
  # Check if coordinates are within the Philippine bounding box
  bbox_check <- all(wnh_hubs$from_lat > 4 & wnh_hubs$from_lat < 21)
  message("Coordinate validity: ", bbox_check)
}
