I have previously used ggtree to make a circular phylogram.
Back then, the tip labels (with geom_tiplab2) would appear as attached, with some tip labels on the outer layer and others deeper within the circular plot:
Today, I was using the exact same code. But I have since updated R and ggtree. However, now, using the same code (I'm quite sure) all tip labels are appearing on the outermost layer of the circular tree. So it appears like so, with all tip labels aligned around the outer length:
What might be the problem? I'd like the tip labels to be like they used to (in the picture above).
Here is my code:
tree <- ggtree(ca, layout = "circular", color = "slategray4", alpha = 0.7, size = 0.5) +
geom_tiplab(size = 1) +
# geom_nodelab(aes(label = node), size = 3) +
geom_rootpoint(color = "slategrey", size = 1) +
geom_rootedge(rootedge = 0.6, size = 0)
Thanks!
EDIT: I "fixed" this by reverting back to R version 4.2.2. Don't know the root cause of the issue.
