## Draw Background for A Data Track On Nodes of caOmicsV bioNet Layout

### Description

Paint (with any color other than white) background for a circular track on each node on caOmicsV bioNetCircos layout. Graphic device and igraph object must exist.

### Usage

        drawBioNetNodeBackground(trackLocations, bgColor=gray(0.9, alpha=0.5))

### Arguments

`trackLocations` | a list returned by getBioNetPlotLocations() function.
`bgColor` | character vector or R color specification for background color

### Value

None

### Author(s)

Henry Zhang

### Examples

        data(bionetPlotDemoData)
        expr <- bionetPlotDemoData$heatmapData[[1]]
        bioNet <- bc3net(expr)
        initializeBioNetCircos(bioNet)

        bioNetGraph <- getBioNetGraph()
        outer <- 1.5
        inner <- 1.0

        nodeCenter <- as.numeric(bioNetGraph$layout[1,])
        plotLocations <- getBioNetPlotLocations(nodeCenter, outer, inner)

        showBioNetNodesLayout()
        eraseBioNetNode()
        drawBioNetNodeBackground(plotLocations)
