## Plots Legend for Color Ramp

### Description

Plots legend for color ramp.

### 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` | Margin. See `par`.
`las` | Orientation of labels on axis. See `par`.
`...` | 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'.

          heights = 1)
    ## End(Not run)
