PoR_coordinates: Coordinates of the Pole of Rotation Reference System

In tectonicr: Analyzing the Orientation of Maximum Horizontal Stress

Coordinates of the Pole of Rotation Reference System

Description

Retrieve the PoR equivalent coordinates of an object

Usage

PoR_coordinates(x, PoR)

Arguments

x	sf or data.frame containing lat and lon coordinates (lat, lon)
PoR	Pole of Rotation. "data.frame" or object of class "euler.pole" containing the geographical coordinates of the Euler pole

Value

PoR_coordinates() returns data.frame with the PoR coordinates (lat.PoR, lon.PoR).

Examples

data("nuvel1")
por <- subset(nuvel1, nuvel1$plate.rot == "na") # North America relative to Pacific plate
data("san_andreas")

# coordinates from sf object
san_andreas.por_sf <- PoR_coordinates(san_andreas, por)
head(san_andreas.por_sf)

# coordinates from data.frame
san_andreas.por_df <- PoR_coordinates(sf::st_drop_geometry(san_andreas), por)
head(san_andreas.por_df)
