Euler pole object

Creates an object of the orientation of the Euler pole axis

Usage

euler_pole(x, y, z = NA, geo = TRUE, angle = NA)

Arguments

x

latitude or x coordinate of Euler pole axis

y

longitude or y

z

z coordinate

geo

logical, TRUE (the default) if Euler pole axis is given in geographical coordinates (latitude, longitude). FALSE if given in Cartesian coordinates (x, y, z)

angle

(optional) Angle of rotation in degrees (CCW rotation if angle is positive)

Value

An object of class "euler.pole" containing the Euler pole axis in both geographical and Cartesian coordinates and the angle of rotation in radians.

Examples

euler_pole(90, 0, angle = 45)
#>   lat lon x y z     angle
#> 1  90   0 0 0 1 0.7853982
euler_pole(0, 0, 1, geo = FALSE)
#>   lat lon x y z angle
#> 1  90   0 0 0 1    NA
