This generator supplies 0 or 1 value depending on the provided coordinates
position on a checkerboard. The `frequency`

determines the number of squares
per unit.

gen_checkerboard(x, y = NULL, z = NULL, t = NULL, frequency = 1, ...)

x, y, z, t | The coordinates to get pattern from |
---|---|

frequency | The frequency of the generator |

... | ignored |
