Problèmes de diagramme d'accords réseau en R
J'ai des données similaires à data.framed comme suit.
d <- structure(list(ID = c("KP1009", "GP3040", "KP1757", "GP2243",

Je souhaite explorer les relations entre les membres de d$ID en utilisant un diagramme d'accords similaire à celui ci-dessous.
Il y a plusieurs options pour le faire dans R. ( Diagramme d'accords dans R ).
Dans mes données, les relations sont selon d$Set (non directionnel) et le regroupement est selon d$Loc. Voici mes tentatives pour cartographier ces relations sous forme de diagramme d'accords.
Tentative 1: utilisation de igraph
J'ai essayé igraph comme suit avec la taille du nœud en fonction du degré.
# Get vertex relationships
sets <- unique(d$Set[duplicated(d$Set)])
rel <- vector("list", length(sets))
for (i in 1:length(sets)) {
rel[[i]] <- as.data.frame(t(combn(subset(d, d$Set ==sets[i])$ID, 2)))
}
library(data.table)
rel <- rbindlist(rel)
# Get the graph
g <- graph.data.frame(rel, directed=F, vertices=d)
clr <- as.factor(V(g)$Loc)
levels(clr) <- c("salmon", "wheat", "lightskyblue")
V(g)$color <- as.character(clr)
# Plot
plot(g, layout = layout.circle, vertex.size=degree(g)*5, vertex.label=NA)
Comment modifier l'intrigue pour ressembler à la première figure? Il semble qu'il n'y ait pas d'options pour modifier igraphlayout.circle.
Tentative 2: utilisation de Circlize
Il semble que les courbes de Bézier plus lisses et le regroupement soient possibles dans le package Rcirclize. Mais ici, je ne suis pas en mesure de regrouper les nœuds ainsi que d'ajuster leur taille en fonction du degré car ils sont tracés en secteurs.
par(mar = c(1, 1, 1, 1), lwd = 0.1, cex = 0.7)
circos.initialize(factors = as.factor(d$ID), xlim = c(0, 10))
circos.trackPlotRegion(factors = as.factor(d$ID), ylim = c(0, 0.5), bg.col = V(g)$color,
bg.border = NA, track.height = 0.05)
for(i in 1:nrow(rel)) {
circos.link(rel[i,1], 0, rel[i,2],0, h = 0.4)
}
Ici cependant, il n'y a pas d'options pour modifier les nœuds. En fait, ils ne peuvent être tracés que sous forme de secteurs? Dans ce cas, existe-t-il un moyen de modifier les secteurs en nœuds circulaires de taille en fonction du degré?
Tentative 3: utilisation de edgebundleR ( https://github.com/garthtarr/edgebundleR )
require(edgebundleR)
edgebundle(g,tension = 0.1,cutoff = 0.5, fontsize = 18,padding=40)
Il semble ici qu'il existe des options limitées pour modifier l'esthétique.
J'ai apporté un tas de changements à edgebundleR. Ce sont maintenant dans le référentiel principal. Le code suivant devrait vous rapprocher du résultat souhaité. exemple en direct

Je déteste ajouter une autre réponse pour un problème différent, mais je ne connais aucun moyen de gérer la question supplémentaire posée dans le commentaire. Le commentaire demandait comment pourrions-nous colorer les bords. Généralement, la réponse serait facile, mais dans ce cas, la réponse nécessite une réécriture d'une grande partie du code dans edgebundleR ou nécessite un hack. J'irai avec le hack ci-dessous.
