Plot A Color Scale for Heatmap

Plot a color scale showing the color ranges of heatmap. One or more tracks should be defined for plots in outside of chromosome ideogram.

Usage

RCircos.Plot.Heatmap.Color.Scale(max.value=NULL, min.value=NULL,
        color.type="BlueWhiteRed", scale.location=1, 
        scale.width=0, scale.height=0)

Arguments

max.value

Numeric, maximum value of heatmap scale

min.value

Numeric, minimum value of heatmap scale

color.type

Character vector for color specification, either "BlueWhiteRed", "GreenWhiteRed", "GreenYellowRed","GreenBlackRed", "YellowToRed", or "BlackOnly". Default is "BlueWhiteRed".
