In ggtree: an R package for visualization of tree and annotation data

Description

filter data for tree annotation layer

Usage

td_filter(..., .f = NULL)

Arguments

...	Expressions that return a logical value.
.f	a function (if any, default is NULL) that pre-operate the data

Details

The 'td_filter()' function returns another function that can be used to subset ggtree() plot data. The function can be passed to the 'data' parameter of geom layer to perform subsetting. All rows that satisy your conditions will be retained.
