renderer_leaflet {processanimateR}

Render as graph on a geographical map

Description

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

Usage

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

scale_max

The maximum factor to be used to scale the process map with when zooming out.

scale_min
