R: Transform polar or cylindrical coordinates to Cartesian...

pol2cart {geometry} | R Documentation

## Transform polar or cylindrical coordinates to Cartesian coordinates.

### Description

The inputs `theta`, `r`, (and `z`) must be the same shape, or scalar. If called with a single matrix argument then each row of `P` represents the polar/(cylindrical) coordinate (`theta`, `r` (, `z`)).

### Usage

    pol2cart(theta, r = NULL, z = NULL)

### Arguments

`theta` | describes the angle relative to the positive x-axis.
`r` | is the distance to the z-axis (0, 0, z).
`z` | (optional) is the z-coordinate

### Value

a matrix `C` where each row represents one Cartesian coordinate (`x`, `y` (, `z`)).
