Using geom_edge_elbow() according to the vignette does not work as expected on my setup.
Any idea why it is so ? I would like to use ggraph to make a "classical" dendrogram with right angles.
Minimal not-working example :
dendrogram <- as.dendrogram(hclust(dist(iris[, 1:4])))
ggraph(dendrogram, 'dendrogram') + geom_edge_elbow()
It gives me the warning:
Warning message:
Removed 298 rows containing non-finite values (stat_edge_elbow).

When I use it on my data, clustered with hclust and dist with default parameters, it gives me "object 'direction' not found.
Thanks for your great work on ggraph otherwise !
