Usage

iplotLegend(colramp, ncol = NULL,
            cex.axis = par("cex.axis"), border = FALSE,
            mar = c(0, 0, 0, 3), las = 1, ...)

Arguments

colramp

Function defining color ramp, e.g. IDPcolorRamp

ncol

Number of individual colors in color ramp. See details.

cex.axis

Magnification to be used for labels.

border

Logical. When TRUE, a border is drawn around the individual colors in the legend.

mar

Additional arguments to par

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

# NOT RUN {
par(oma = rep(2, 4))
layout(matrix(c(1, 2), ncol = 2),
      width = c(lcm(par("csi")*5*2.54), 1),
      heights = 1)
# }
# NOT RUN {
iplotLegend(IDPcolorRamp, ncol = 15)
# }
