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

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

Arguments

data

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

lineResolution

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

mapRegion

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

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_country(BITR_geocode)
#> Regions defined for each Polygons
## Mapping only North America output <- plot_net_country(BITR_geocode, mapRegion = 'North America')
#> Regions defined for each Polygons
## Change the transparency of lines by modifying the lineAlpha parameter output <- plot_net_country(BITR_geocode, lineAlpha = 0.2)
#> Regions defined for each Polygons
## Change the curvature of lines by modifying the lineResolution paramater output <- plot_net_country(BITR_geocode, lineResolution = 30 )
#> Regions defined for each Polygons
## With all arguments: output <- plot_net_country(BITR_geocode, mapRegion = 'North America', lineAlpha = 0.2, lineResolution = 30)
#> Regions defined for each Polygons
