Creating Networks

We have thus

# Load necessary packages
library(readxl)
library(tidyverse)
library(openxlsx)
library(igraph)

# Set Working Directory
setwd("C:/Users/heblj/OneDrive/Career/Professional_Portfolio/Network_Analysis/MigrationAmericas_NetworkAnalysis/Immigration_Networks")

  ### Load the graphs ----
      load("Constructing_Networks/g_1990.R")
      load("Constructing_Networks/g_2000.R")
      load("Constructing_Networks/g_2010.R")
      load("Constructing_Networks/g_2020.R")

Now let’s create the visualizations.

      # Defined the preferred layout to use in subsequent networks
      layout_preferred <- layout_with_fr(g_1990)
      
  ### Graph based on Degree ----
      ### Degree Total ----
      
      plot(g_1990,
           main = "Migration 1990",
           sub = "Vertex size by Degree",
           layout = layout_preferred,
           edge.arrow.size = 0.5,
           vertex.size = V(g_1990)$DegT^1.5,
           vertex.color = V(g_1990)$DegT,
           vertex.label.font = 2,
           vertex.label = V(g_1990)$code)
