Build node table for continuous phylogeography

build_nodes(
  treedata,
  lon = "location1",
  lat = "location2",
  height = "height_median",
  digits = 2,
  most_recent_sample = NULL,
  debug = getOption("ggphylogeo.debug", FALSE)
)

Arguments

treedata: treedata object with phylogeographic annotations
lon: name of longitude column prefix (default: "location1")
lat: name of latitude column prefix (default: "location2")
height: column name used for node ages (default: "height_median")
digits: numeric digits for rounding coordinates (default: 2)
most_recent_sample: Date or numeric year (e.g. 2019) used to calibrate ages to actual dates. If NULL (default) no calibration is performed.
debug: logical debug messages

Value

A data.frame with columns: node, lon, lat, age, istip, label
