Width of the legend strip, that is, the length of its
shorter dimension. Defaults to 1/30 of the axis range.
len
Length of the legend strip, that is, the length of its
longer dimension. Defaults to 1/4 of the axis range.
colmax
Colour at the maximum density, either as a built-in R
colour name (one of colors()) or an RGB hex value. Defaults
to par("fg") or its lattice equivalent, which is
"black" by default.
colmin
Colour to shade the minimum density, likewise.
Defaults to "white". If this is set to "transparent",
and the current graphics device supports transparency (see rgb), then
overlapping strips will merge smoothly.
gamma
Gamma correction to apply to the colour palette, see denstrip.
horiz
Legend strip drawn vertically (FALSE) or
horizontally (TRUE).
max
Maximum density on the legend, which is represented by
colmax. With the default of 1, the legend indicates the
mapping of colours to proportions of the maximum density.
nticks
Number of tick marks on the axis adjacent to the
legend, if ticks not supplied.
ticks
Positions of numbered ticks on the axis adjacent to the
legend. Defaults to nticks equally spaced ticks between 0 and
the maximum density.
value.adj
Extra adjustment for the axis labels to the right
(if horiz=FALSE) or downwards (if horiz=TRUE).
cex
Text expansion. Defaults to par("cex") * 0.75 or
trellis.par.get("axis.text")$cex * 0.75.
main
Text to place above the legend.
lattice
Set this to TRUE to make denstrip.legend
a lattice panel function instead of a base graphics function. panel.denstrip.legend(x,...) is equivalent to
denstrip.legend(x, lattice=TRUE, ...).
...
Other arguments passed to panel.denstrip.legend.

### TODO if max not supplied - ticks are not meaningful.
### In help example, find actual max dens used for densregion
