In dilp: Reconstruct Paleoclimate and Paleoecology with Leaf Physiognomy

Test if site leaf physiognomy falls within the physiognomic space of the DiLP calibration dataset

Description

dilp_cca plots a canonical correspondence analysis (CCA) ordination of the leaf physiognomic space represented in the calibration dataset of Peppe et al. (2011). The fossil sites being tested are placed along the CCA axes. If a fossil site falls outside of the plotted calibration space, paleoclimate reconstructions for that fossil site should be treated with caution.

Usage

dilp_cca(
  dilp_table,
  physiognomy_calibration = physiognomyCalibration,
  climate_calibration = climateCalibration
)

Arguments

dilp_table	The results of a call to dilp()
physiognomy_calibration	A physiognomic calibration dataset. Defaults to an internal version of physiognomy_calibration_data.
climate_calibration	A climate calibration dataset. Defaults to an internal version of climate_calibration_data.

Value

A ggplot2 plot
