## An Extension of Wilkinson's Algorithm for Position Tick Labels on Axes

### Description

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

### Usage

      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))

### Arguments

`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)

### Value

vector of axis label locations
