Today ggtree received 100 stars on and I found the paper was online at the same day by the tweet:

I am quite exciting about it. Now ggtree is citable by doi:10.1111/2041-210X.12628.

In the review period, ggtree had already been cited by several papers:

1. https://doi.org/10.7717/peerj.976

Annotating phylogenetic tree with image files (i.e. secondary structure).

The ggtree paper provides several comprehensive and reproducible examples. It can be a good reference for complex tree annotation. My slides in 9th China R conference summarized the functionalities that ggtree provided.

More information can be found in ggtree homepage. Hope you have fun with ggtree.
