`extended`

is an enhanced version of Wilkinson's
optimization-based axis labeling approach. It is
described in detail in our paper. See the references.

```
extended(dmin, dmax, m, Q = c(1, 5, 2, 2.5, 4, 3),
only.loose = FALSE, w = c(0.25, 0.2, 0.5, 0.05))
```

`dmin` |
minimum of the data range |

`dmax` |
maximum of the data range |

`m` |
number of axis labels |

`Q` |
set of nice numbers |

`only.loose` |
if true, the extreme labels will be outside the data range |

`w` |
weights applied to the four optimization components (simplicity, coverage, density, and legibility) |

vector of axis label locations
