News of ggtree
A new version of ggtree that works with ggplot2 (version >= 2.0.0) is now availabel.
new layers
Some functions, add_legend, hilight, annotation_clade and annotation_clade2 were removed. Instead we provide layer functions, geom_treescale
, geom_hilight
and geom_cladelabel
. You can use +
operator to add layers using these layer functions.
In addtion, we provide geom_point2
, geom_text2
and geom_segment2
which works exactly as geom_point
, geom_text
and geom_segment
except they allow ggtree users to do subsetting.
rescale tree
Most of the phylogenetic trees are scaled by evolutionary distance (substitution/site), in ggtree
we can re-scale a phylogenetic tree by any numerical variable inferred by evolutionary analysis. For example using substitution rate to scale a time-scaled tree inferred by BEAST, or using dN/dS to re-scale a tree analyzed by CodeML.
New Hampshire eXtended format (NHX) supported
This is a feature request from ggtree
user. The NHX format is also commonly used in phylogenetic software (e.g. PHYLODOG, RevBayes, etc).

The original vignette was too long and I split them into several short ones. These vignettes should be more easy to follow. You can access the vignette via http://guangchuangyu.github.io/ggtree/. More examples and detail explanation were provided. If there are something that I didn’t explain well or if you have suggestions for changes or improvements, submit an issue, or (even better) fork ggtree, make modifications and submit a pull request.
I appreciate your help in improving ggtree
