extended

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
