Creates a network diagram of coauthors' addresses linked by reference, and with nodes arranged geographically

This function takes an addresses data.frame, links it to an authors__references dataset and plots a network diagram generated for individual points of co-authorship.

Usage

plot_net_address(
  data,
  mapRegion = "world",
  lineResolution = 10,
  lineAlpha = 0.5
)

Arguments

data

the address element from the list outputted from the authors_georef() function, containing geocoded address latitude and longitude locations.

mapRegion

what portion of the world map to show. possible values include "world", "North America", "South America", "Australia", "Africa", "Antarctica", "Eurasia"

lineResolution

the resolution of the lines drawn, higher numbers will make smoother curves default is 10.

lineAlpha

transparency of the lines, fed into ggplots alpha value. Number between 0 - 1.

Examples

## Using the output of authors_georef (e.g., BITR_geocode)
data(BITR_geocode)
## Plots the whole world
output <- plot_net_address(BITR_geocode)

## Just select North America
output <- plot_net_address(BITR_geocode, mapRegion = 'North America')

## Change the transparency of lines by modifying the lineAlpha parameter
output <- plot_net_address(BITR_geocode, lineAlpha = 0.2)
                 
## Change the curvature of lines by modifying the lineResolution paramater
output <- plot_net_address(BITR_geocode, lineResolution = 30 )
                 
output <- plot_net_address(BITR_geocode, mapRegion = 'North America', lineAlpha = 0.2,
                 lineResolution = 30)
