I would like to visualize a phylogenetic tree with circles at the tips. The tips should have white fill, but a black border. How do I do this in ggtree?
Here is a MWE:
tree <- rtree(50)
ggtree(tree) + geom_tippoint(size=3, fill="white", color="black")
ggtree(tree) + geom_point(size=3, fill="white", color="black")
With both the
geom_point functions, the circles are solidly black despite the presence of
fill="white". What am I doing wrong?
