Details

A color ramp of ncol+1 individual colors is plotted, starting with the background color (= color 0). When ncol = NULL a color ramp of 101 individual colors is plotted. The color at the bottom is labeled by '0', the color at the top by 'max'.

Examples

if (FALSE) {
par(oma = rep(2, 4))
layout(matrix(c(1, 2), ncol = 2),
      width = c(lcm(par("csi")*5*2.54), 1),
      heights = 1)}
iplotLegend(IDPcolorRamp, ncol = 15)
