Render as graph on a geographical map

This renderer uses Leaflet to draw the nodes and egdes of the process map on a geographical map.

renderer_leaflet(
  node_coordinates,
  edge_coordinates = data.frame(act_from = character(0), act_to = character(0), lat =
    numeric(0), lng = numeric(0), stringsAsFactors = FALSE),
  layer = c(paste0("new L.TileLayer('", tile, "',"), paste0("{ attribution : '",
    attribution_osm(), "'})")),
  tile = "http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png",
  options = list(),
  grayscale = TRUE,
  icon_act = icon_marker(),
  icon_start = icon_circle(),
  icon_end = icon_circle(),
  scale_max = 4,
  scale_min = 0.25
)

Arguments

node_coordinates: A data frame with node coordinates in the format `act`, `lat`, `lng`.
edge_coordinates: A data frame with additional edge coordinates in the format `act_from`, `act_to`, `lat`, `lng`.
layer: The JavaScript code used to create a Leaflet layer. A TileLayer is used as default value.
tile: The URL to be used for the standard Leaflet TileLayer.
options: A named list of leaflet options, such as the center point of the map and the initial zoom level.
grayscale: Whether to apply a grayscale filter to the map.
icon_act: The SVG code used for the activity icon.
icon_start: The SVG code used for the start icon.
icon_end: The SVG code used for the end icon.
scale_max: The maximum factor to be used to scale the process map with when zooming out.
scale_min: The minimum factor to be used to scale the process map with when zooming in.

Value

A rendering function to be used with animate_process

Examples

data(example_log)

# Animate the example process with activities placed in some locations
animate_process(example_log,
  renderer = renderer_leaflet(
    node_coordinates = data.frame(
       act = c("A", "B", "C", "D", "ARTIFICIAL_START", "ARTIFICIAL_END"),
       lat = c(63.443680, 63.426925, 63.409207, 63.422336, 63.450950, 63.419706),
       lng = c(10.383625, 10.396972, 10.406418, 10.432119, 10.383368, 10.252347),
       stringsAsFactors = FALSE),
    edge_coordinates = data.frame(
       act_from = c("B"),
       act_to = c("C"),
       lat = c(63.419207),
       lng = c(10.386418),
       stringsAsFactors = FALSE),
    options = list(center = c(63.412273, 10.399590), zoom = 12)),
  duration = 5, repeat_count = Inf)
