clock2cart

Convert Clock Coordinates to Cartesian Coordinates

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

clock2cart(rho, phi, circle)

`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`.

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

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)
