Generates a function for labeling bootstrap values on a phylogenetic tree.
Is not a labeling function itself, but returns one.
The returned function is specialized for labeling bootstrap values.
Note that the function that
is returned has two completely different arguments from the four 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 nodeplotdefault for a simpler example.
The main purpose of this and nodeplotdefault is to
provide a useful default function generator for arbitrary and
bootstrap node labels, respectively, and also to act as
examples of functions that can successfully interact with
plot_tree to add node labels to the graphic.
nodeplotboot(highthresh=95L, lowcthresh=50L, size=2L, hjust=-0.2)
highthresh |
(Optional). A single integer between 0 and 100. Any bootstrap values above this threshold will be annotated as a black filled circle on the node, rather than the bootstrap percentage value itself. |
lowcthresh |
(Optional). A single integer between 0 and 100,
less than |
size |
(Optional). Numeric. Should be positive. The
size parameter used to control the text size of taxa labels.
Default is |
hjust |
(Optional). The horizontal justification of the
node labels. Default is |
A function that can add a bootstrap-values layer to the tree graphic. The values are represented in two ways; either as black filled circles indicating very high-confidence nodes, or the bootstrap value itself printed in small text next to the node on the tree.
