ITNimvex function

ITN - Exports vs Imports Plot

The following function produces a plot showing imports (in degree) vs exports (out degree). This allows us to identify whether in the ITN, countries that export high levels also import high levels. The plot can be produced for either weighted or binary import and export ties.

ITNimvex(gs, weighted)

Arguments

• gs: International Trade Network - igraph object
• weighted: TRUE - plot import strength vs export strength. FALSE - Import count Vs export count

Returns

Imports Vs Exports Plot

Examples

require(igraph)

##Create random International Trade Network (igraph object)
ITN<-erdos.renyi.game(75,0.05,directed = TRUE)

##Add edge weights
E(ITN)$weight<-runif(ecount(ITN), 0, 1)

##Plot binary import vs exports
imvex_plot<-ITNimvex(ITN,FALSE)
