Description

Wrapper for plotColorLegend to plot legend for given range

Usage

plotColorLegend2(
  x0 = NULL,
  x1 = NULL,
  y0 = NULL,
  y1 = NULL,
  zlim,
  fullzlim = zlim,
  zfun = identity,
  z2col = num2col,
  N = 100,
  ntic = 5,
  leg = NULL,
  title = NULL,
  title.adj = c(0, -0.5),
  horizontal = FALSE
)

Arguments

x0, x1, y0, y1	rectange coordinates of the legend in nfc coordinates
zlim	numeric vector with two items. Range to show, trimmed to fullzlim if wider.
fullzlim	numeric vector with two items. Full range to be considered.
zfun	transformation for value (gradient will be drawn along transformed value). Identity, log1p, sqrt, ets.
z2col	function to transform numbers to colors
N	number of steps in the gradient
ntic	desired number of tics
leg	tics values, if NULL (default) estimated automatically
