nodeplotdefault: Generates a default node-label function
In phyloseq: Handling and analysis of high-throughput microbiome census data

Description Usage Arguments Value See Also Examples

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.

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

`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`.

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