Description

Converts clock coordinates (rho, phi) to cartesian coordinates (x, y).

Usage

clock2cart(rho, phi, circle)

Value

Data frame with

x, y

Cartesian coordinates.

Arguments

rho

Distance of point from center of coordinate system.

phi

Angle between North (12 o' clock), center and the point, measured clockwise.

circle

Defines the full circle in the units of phi.
