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

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
