the edge widths don't change: geom_edge_link(aes(width = weight))

[mnakaya5]

#144 This issue seems to be closed, however, I am facing the same issue now and referring to the previous thread to solve for ddhodge. Any thoughts as to what might be going on?

ddHodge part

Specify the indices of starting root cluster(e.g."4").

g <- diffusionGraph(data_csv,group=="5",k=7,npc=100,ndc=40,s=2)

Visualization

dggraph <- function(g,...)
ggraph(g) + theme_void() +
geom_edge_link(
aes(width=weight),
colour="black",
arrow=arrow(length=unit(2.4,"mm")),
end_cap = circle(1.2,'mm'),
) + scale_edge_width(range=c(0.2,0.5)) +
geom_node_point(...)
