R: Convert Clock Coordinates to Cartesian Coordinates

clock2cart {IDPmisc} | R Documentation

## 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.

### Examples

    ## 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)
