Not sure if a bug or a feature but the coloring depends on the alpha (or edge_alpha) aesthetic being set:
ggraph(highschool) +
geom_edge_bundle_force(aes(color=as.factor(year), alpha = 0))
That is for sure a bug
library(ggraph)
#> Loading required package: ggplot2
ggraph(highschool,"stress") +
geom_edge_bundle_force(aes(color=as.factor(year), alpha = 0))
ggraph(highschool, "stress") +
geom_edge_bundle_force(aes(color = as.factor(year)))

The bug is here in StatEdgeBundleForce0$compute_panel function you should return " cbind(edges, data[edges$group, !names(data) %in% c("x", "y", "xend", "yend", "PANEL", "group"), drop = FALSE]) "
