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")
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 |
Value
a list of coordinates, in cartesian form or dec, inc, int form following the input

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)
