In Rclade: Automated Deep-Time Phylogenetic Tree Collapsing and Visualization

Apply coordinate-system clip="off" (the only clip application point)

Description

Collapsed-triangle vertices (especially the MRCA apex) often extend beyond the tip-based y-axis range, so the plot panel must NOT clip them. This helper is the single, sanctioned place to add clip = "off":

• rectangular -> coord_cartesian(clip = "off")

• circular/fan -> coord_polar(theta = "y", clip = "off")

Usage

add_clip_off(p, layout = "rectangular")

Arguments

p	A ggplot object.
layout	"rectangular" or "circular".

Details

A utils::packageVersion("ggplot2") guard protects against ggplot2 < 3.5.0 (which does not support clip = "off"): in that case we log_warning and skip clip rather than silently mis-rendering.

Value

The ggplot object with the appropriate clip-off coordinate added.
