runif_sphere | R Documentation |

Uniform sampling on a sphere or in a sphere, in arbitrary dimension.

```
runif_on_sphere(n, d, r = 1)
runif_in_sphere(n, d, r = 1)
```

`n` |
number of simulations |

`d` |
dimension of the space |

`r` |
radius of the sphere |

The simulations in a `n`

times `d`

matrix.

```
sims <- runif_on_sphere(20, d = 2)
plot(sims, xlim = c(-1, 1), ylim = c(-1, 1), asp = 1, pch = 19)
sims <- runif_in_sphere(100, d = 2)
plot(sims, xlim = c(-1, 1), ylim = c(-1, 1), asp = 1, pch = 19)
```
