Flowmap.blue R widget

WORK IN PROGRESS

This is a Flowmap.blue widget for R. It produces an interactive flow map representing numbers of movements between locations (origin-destination data).

You might also consider using this pure R flowmapping library: https://github.com/JohMast/flowmapper

As an alternative, you may also consider using R to populate a spreadsheet for publishing on Flowmap.blue as described in this excellent blog post.

Installation

From CRAN (when available):

# install.packages("flowmapblue")

To install from GitHub you will need to install remotes if you don’t have it yet:

if (!require("remotes")) install.packages("remotes")

remotes::install_github("FlowmapBlue/flowmapblue.R",
  force = TRUE, dependencies = TRUE)

Quick example

Setup your Mapbox access token. You can obtain a free token by signing up at Mapbox.

Sys.setenv(MAPBOX_API_TOKEN = "YOUR_MAPBOX_ACCESS_TOKEN")

# load locations and flows for Switzerland
data(ch_locations)
data(ch_flows)

flowmap <- flowmapblue(
 ch_locations,
 ch_flows,
 mapboxAccessToken = Sys.getenv('MAPBOX_API_TOKEN'),
 clustering = TRUE,
 darkMode = TRUE,
 animation = FALSE
)

# view the map
flowmap

Here is a nice intro blog post by Paula Moraga.
