GitHub - schochastics/roughnet: R package to draw sketchy, hand-drawn-like networks with roughjs (original) (raw)
roughnet
Using the java script library rough.js to draw sketchy, hand-drawn-like networks.
(Checkout ggrough for turning general ggplot objects into sketchy drawings)
Installation
You can install the developers version of roughnet with:
install.packages("remotes")
remotes::install_github("schochastics/roughnet")
Example
The package currently only works with {{igraph}} objects by setting styling elements as vertex/edge attributes.
library(roughnet) library(igraph)
g <- make_graph("Zachary") V(g)$shape <- "circle" V(g)$shape[c(1,34)] <- "rectangle" V(g)$fill <- c("#E41A1C", "#377EB8", "#4DAF4A", "#984EA3")[membership(cluster_louvain(g))] V(g)$fillstyle <- c("hachure", "zigzag", "cross-hatch", "dots")[membership(cluster_louvain(g))] V(g)$color <- "black" V(g)$size <- 30 V(g)$stroke <- 2 E(g)$color <- "#AEAEAE" roughnet(g,width = 960,height = 600)
You can save the plot with the function save_roughnet()
(needs {{pagedown}} to be installed.)
install.packages("pagedown")
p <- roughnet(g,width = 960,height = 600) save_roughnet(p,"karate.png")
Extended Example
The package also allows to place labels in or around vertices and implements some custom vertex shapes.
install.packages(c("signnet","graphlayouts"))
library(signnet) library(graphlayouts) library(dplyr)
data("avatar") # Allies/Enemies relations in Avatar: The Last Airbender
main <- induced_subgraph(avatar,which(V(avatar)$main)) #only use the main characters
#calculate layout w <- ifelse(E(main)$sign==1,3,1) xy <- layout_with_stress(main,weights = 1/w)
V(main)$x <- xy[,1] V(main)$y <- xy[,2]
