## Heatmap Plot on caOmicsV bioMatrix Layout

### Description

Headmap plot method for bioMatrix layout. This function will plot all rows of the input data. bioMatrix layout and graphic device must be initialized first.

### Usage

        plotBioMatrixHeatmap(exprData, topAdjust=0, bottomAdjust=0,
                maxValue=NULL, minValue=NULL,
                heatmapColor="BlueWhiteRed", skipPlotRow=0)

### Arguments

`exprData` | numeric matrix (log2 values) with row names
`topAdjust` | non-negative numeric, height of top y coordinate should be reduced to show different layers, default 0
`bottomAdjust` | non-negative numeric, height of bottom y coordinate should be reduced for a small rectangle, default 0
`maxValue` | numeric, value for highest color in heatmap, set to NULL to use the maximum value in expression dataset
`minValue` | numeric, value for lowest color in heatmap, set to NULL to use the minimum value in expression dataset
`heatmapColor` | character vector,one of "BlueWhiteRed", "GreenWhiteRed", "GreenYellowRed", "GreenBlackRed" , or "YellowToRed"
`skipPlotRow` | non-negative integer, total rows on plot area that should be skipped, default 0

### Value

None

### Examples

        initializeBioMatrixPlot(numOfGenes=1, numOfSamples=50)
        showBioMatrixPlotLayout("Gene", paste("Sample", 1:50),  "Diagnosis")

        data(biomatrixPlotDemoData)
        exprData <- biomatrixPlotDemoData$heatmapData[[1]]
        exprData <- matrix(exprData[1, 1:50], nrow=1)
        plotBioMatrixHeatmap(exprData, maxValue=3, minValue=-3)
