nodeplotdefault: Generates a default node-label function

In joey711/phyloseq: Handling and analysis of high-throughput microbiome census data

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.
