add_geo_events: Add geological event bands (e.g., GOE, NOE) to a tree plot

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

Add geological event bands (e.g., GOE, NOE) to a tree plot

Description

Events are drawn as semi-transparent vertical bands covering the full vertical extent of the tree (but not the geological timescale panels).

Usage

add_geo_events(p, tree, events = NULL)

Arguments

p	ggplot object
tree	phylo object (edge lengths in Ma)
events	Event specification. Can be: NULL (default): shows built-in events (GOE = 2400–2000 Ma, NOE = 800–550 Ma). A data.frame with columns name, age_min (Ma), age_max (Ma), and optionally color. A list of named lists, each with elements name, age_min, age_max, and optionally color. A named list with a single event (shorthand). If only age is provided (instead of age_min/age_max), a default bandwidth of +/- 200 Ma is used.

Value

ggplot object
