Many apologies for not answering your issue before.
As I'm sure you found out, yes, all network packages allow you to delete edges that you do not show in a graph. Below is an example with igraph (which can also be coded with the network package).
library(igraph)
library(ggnetwork)
n <- igraph::random.graph.game(10, 0.3)
E(n)$weight <- sample(c(1, 2), igraph::gsize(n), replace = TRUE)
# delete unwanted edges
n_for_plot <- delete_edges(n, which(E(n)$weight < 2))
# visualize plot-version of graph
ggplot(n_for_plot, aes(x, y, xend = xend, yend = yend)) +
geom_edges() +
geom_nodes() +
theme_blank()
Hi! First of all I want to thank you for the great job with this package. I am working with a weighted network of investments, and I was wondering whether a way exists to plot just part of the edges in the network, but keeping the nodes in the plot. (say, only those edges having weight greater than a minimum threshold). Is it possible to do it with ggnetwork? In case it is not, what package could fit for the purpose? thank you for any help
