Create a `PointPattern-class`

object representing a 2D point
pattern with 1,4,5,6,7,8 or 9 points lying in a rectangle.

1 |

`n` |
the number of points. Must be 1,4,5,6,7,8 or 9. Default, 4. |

`h` |
the horizontal side length of the rectangle. Default, 1. |

`v` |
the vertical side length of the rectangle. Default, h. |

`h3` |
if |

When `n`

=4, the four points lie at the four corners of the
rectangle. When `n`

=5, the fifth point lies at the center of the
rectangle. When `n`

=6 (and `h3`

is `TRUE`

), four points
lie at the rectangle corners and the two other points lie at the
centres of the top and bottom edges. When `n`

=7 (and `h3`

is
`TRUE`

), the point pattern consists of 3 horizontal alignments of
2, 3 and 2 points. When `n`

=8 (and `h3`

is `TRUE`

), the point
pattern consists of 3 horizontal alignments of 3, 2 and 3 points.
When `n`

=9, the point pattern consists of 3 (horizontal or
vertical) alignments of 3 points.

object.
