clock2cart {IDPmisc}

Convert Clock Coordinates to Cartesian Coordinates

Description

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

Usage

clock2cart(rho, phi, circle)

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.

Details

Be aware that in clock coordinates and polar coordinate the angle phi is differently defined!

Value

Data frame with

x, y

Cartesian coordinates.

## an easy way to plot a circle
xy <- clock2cart(rho=rep(1,33),phi=seq(0,to=360,length.out=33),circle=360)
plot(xy)
