R: Transform spherical coordinates to Cartesian coordinates

sph2cart {geometry} | R Documentation

## Transform spherical coordinates to Cartesian coordinates

### Description

The inputs `theta`, `phi`, and `r` must be the same shape, or scalar. If called with a single matrix argument then each row of `S` represents the spherical coordinate (`theta`, `phi`, `r`).

### Usage

    sph2cart(theta, phi = NULL, r = NULL)

### Arguments

`theta` | describes the angle relative to the positive x-axis.
`phi` | is the angle relative to the xy-plane.
`r` | is the distance to the origin `(0, 0, 0)`. If only a single return argument is requested then return a matrix `C` where each row represents one Cartesian coordinate (`x`, `y`, `z`).
