StratigrapheR (version 1.3.1)

transphere: Convertion between declinaison/inclination/intensity and cartesian coordinates

Description

Convertion between declinaison/inclination/intensity and cartesian coordinates (modified from RFOC package)

Usage

transphere(dec = NA, inc = NA, int = 1, x = NA, y = NA, z = NA, into = "other")

Value

a list of coordinates, in cartesian form or dec, inc, int form following the input

Arguments

dec

declination of the data; it is the angle from the north taken on an horizontal plane. It is measured clockwise from North and ranges from 0 to 360° (Tauxe 2010). Values outside this range are corrected by incfix().

inc

inclination of the data; it is the angle from the horizontal, is positive downward, and ranges from +90° for straight down to -90° for straight up (Tauxe, 2010). Values outside this range are corrected by incfix().

int

intensity of the data. Defaults to one (unit sphere).

x, y, z

cartesian coordinates. x is the North, y the East, and z straight down. If dec and inc are not provided they are used to be converted back in dec, inc and int data. Output is corrected by incfix().

into

overriding parameter for generalisation: if "dii" dec, inc and int will remain as they are, and if "xyz" cartesian coordinates will remain as they are

Examples

transphere(dec = c(65,135), inc = c(32,74))

l <- transphere(dec = c(65,135), inc = c(32,74))
transphere(x = l$x, y = l$y, z = l$z)
