cart2pol {geometry} | R Documentation |
Transform Cartesian coordinates to polar or cylindrical coordinates.
Description
The inputs x
, y
(, and z
) must be the same shape, or
scalar. If called with a single matrix argument then each row of C
represents the Cartesian coordinate (x
, y
(, z
)).
Usage
cart2pol(x, y = NULL, z = NULL)
Arguments
x |
x-coordinates or matrix with three columns |
y |
y-coordinates (optional, if |
z |
z-coordinates (optional, if |
Value
A matrix P
where each row represents one
polar/(cylindrical) coordinate (theta
, r
, (,
z
)).
