5.11 Labeling Points in a Scatter Plot - R Graphics 5.11.3 Discussion. Using geom_text_repel or geom_label_repel is the easiest way to have nicely-placed labels on a plot. It makes automatic (and random) decisions about label placement, so if exact control over where each label is placed, you should use annotate() or geom_text().. The automatic method for placing annotations using geom_text() centers each annotation on the x and y coordinates. Visualizing and Annotating Phylogenetic Trees with R+ggtree Let's finally label the tips. # create the basic plot p <- ggtree(tree) # add node points p + geom_nodepoint() # add tip points p + geom_tippoint() # Label the tips p + geom_tiplab() Exercise 2
