Hello,

Trying ggtree for the first time, it is very impressive.

However, I'm having trouble to get longer labels displayed

library(ggtree)
tree<-read.tree(text="(Organism1.006G249400.1:0.03977,(Organism2.022118m:0.01337,(Organism3.J34265.1:0.00284,Organism4.G02633.1:0.00468)0.51:0.0104):0.02469);")
jpeg("ggtree_phyltree.jpg")
ggtree(tree) + geom_tiplab(size=2)
dev.off()

And tried this:
ggtree(tree, aes(color=branch.length)) +
scale_color_continuous(low="green", high="red") +
geom_text(aes(label=label), size=2, color="purple", hjust=-0.3) +
        theme(legend.position="bottom") + geom_text(aes(label=node))

but it only displays till "Organism".  Also tried adjusting margins with
mar() and par(mai=c(2,0.82,0.82,6)) still no luck.

Don't know how to go about getting the full Gene names displayed on the
tree.

Thanks in advance,
Alan

This is because the units are in two different spaces (data & pixel).

you can use xlim to get more space for text.

try:

ggtree(tree) + geom_tiplab() + ggplot2::xlim(0, 0.06)
