collapse_range: Collapse nodes and ranges based on divergence times

Description

This function collapses nodes and geographic ranges based on species' divergence times at various time depths.

Usage

collapse_range(
  x,
  tree,
  n,
  species = "species",
  grids = "grids",
  format = "wide"
)

Value

Two community data frames: the collapsed community data and original community data

Arguments

x

A community matrix or data frame.

tree

A phylogenetic tree.

n

Time depth to slice the phylogenetic tree (often in millions of years for dated trees).

species

If format = “long” (the default), the column with the species name.

grids

The column with the sites or grids if format = “long”.

format

Format of the community composition data: “long” or “wide” with species as columns and sites as rows.
