knitr::opts_chunk$set( collapse = TRUE, comment = "#>" )
library(netplot) library(igraph) library(sna) library(ggraph) # We will use the UKfaculty data from the igraphdata package data("UKfaculty", package = "igraphdata") # With a fixed layout set.seed(225) l_ukf <- layout_with_fr(UKfaculty)
Since igraph and statnet do the plotting using base system graphics, we can't put everything in the same device right away. Fortunately, the gridGraphics
R package allows us to reproduce base graphics using the grid
system, which, in combination with the function gridExtra::grid.arrange
will let us put both base and grid graphics in the same page. First me write a func
# Function to map base to grid map_base_to_grid <- function(fun) { gridGraphics::grid.echo(fun) grid::grid.grab() }
# Mapping base to grid ig <- map_base_to_grid(function() plot(UKfaculty, main = "igraph")) nw <- map_base_to_grid(function() gplot(as.matrix(as_adj(UKfaculty)), coord = l_ukf, main = "sna"))
nplot(UKfaculty, layout = l_ukf, main="netplot") grid::grid.text("netplot", x = .05, y=.9) np <- grid::grid.grab()
Here is an example with ggraph
ggraph::ggraph(UKfaculty, layout = l_ukf) + ggraph::geom_edge_arc() + ggraph::geom_node_point() + ggplot2::ggtitle("ggraph") gg <- grid::grid.grab()
# Putting all together gridExtra::grid.arrange(ig, nw, gg, np, nrow=2, ncol=2)
To arrange multiple plots in the same page we can use the grid.arrange
function from the gridExtra
package
x_igraph <- sample_smallworld(1, 20, 4, .05) x_network <- intergraph::asNetwork(x_igraph) l <- layout_nicely(x_igraph) # Putting two plots in the same page (one using igraph and the other network) gridExtra::grid.arrange( nplot(x_igraph, layout = l), nplot(x_network, layout = l), ncol=2, nrow=1 )
gridExtra::grid.arrange( nplot(UKfaculty, layout = l_ukf, vertex.size.range = c(.025, .025)), nplot(UKfaculty, layout = l_ukf, vertex.size.range = c(.01, .025)), nplot(UKfaculty, layout = l_ukf, vertex.size.range = c(.01, .025, 4)), nplot(UKfaculty, layout = l_ukf, vertex.size.range = c(.02, .05, 4)), ncol=2, nrow=2 )
