R Documentation

Calculate distance between two features

Description

This function calculates the distance between the first features of two layers or coordinates. Note: This function only works with proxy objects as it returns a numeric value to R.

Usage

turf_distance(
  proxy,
  layer_id = NULL,
  layer_id_2 = NULL,
  data = NULL,
  coordinates = NULL,
  coordinates_2 = NULL,
  units = "kilometers",
  input_id = "turf_distance_result"
)

Arguments

`proxy`	A mapboxgl_proxy or maplibre_proxy object.
`layer_id`	The ID of the first layer or source (mutually exclusive with data and coordinates).
`layer_id_2`	The ID of the second layer or source (required if layer_id is used).
`data`	An sf object for the first geometry (mutually exclusive with layer_id and coordinates).
`coordinates`	A numeric vector of length 2 with lng/lat coordinates for the first point (mutually exclusive with layer_id and data).
`coordinates_2`	A numeric vector of length 2 with lng/lat coordinates for the second point (required if coordinates is used).
`units`	The units for the distance calculation. One of "meters", "kilometers", "miles", etc.
`input_id`	Character string specifying the Shiny input ID suffix for storing the distance result. Default is "turf_distance_result". Result will be available as `input[[paste0(map_id, "_turf_", input_id)]]`.
