nodeplotdefault {phyloseq} | R Documentation

## Generates a default node-label function

### Description

Is not a labeling function itself, but returns one. The returned function is capable of adding whatever label is on a node. Note that the function that is returned has two completely different arguments to those listed here: the plot object already built by earlier steps in `plot_tree`, and the `data.frame` that contains the relevant plotting data for the nodes (especially `x, y, label`), respectively. See `nodeplotboot` for a more sophisticated example. The main purpose of this and `nodeplotboot` is to provide a useful default function generator for arbitrary and bootstrap node labels, respectively, and also to act as examples of functions that will successfully interact with `plot_tree` to add node labels to the graphic.

### Usage

    nodeplotdefault(size=2L, hjust=-0.2)

### Arguments

`size` | (Optional). Numeric. Should be positive. The size parameter used to control the text size of taxa labels. Default is `2`. These are ggplot2 sizes.
`hjust` | (Optional). The horizontal justification of the node labels. Default is `-0.2`.

### Value

A function that can add a node-label layer to a graphic.
