treeForcePositionLabels: Determine position for segment labels in force-directed...

In farrellja/URD: URD

Description

Finds cells near the end of each tip, and attempts to calculate a vector from them to determine a good location for a label near each tip. Called automatically by treeForceDirectedLayout, but can be re-run if needed.

Usage

treeForcePositionLabels(object, label.spacing = 5)

Arguments

object	An URD object
label.spacing	(Numeric) Length of vector from final cell in each tip to label

Value

A data.frame with rows as tips, and columns containing labels and coordinates. This is normally stored in @tree$walks.force.labels.

Examples

object@tree$walks.force.labels <- treeForcePositionLabels(object, label.spacing=2) # Move labels closer
