`beddata`	genomic data to be plotted (in bed format)
`chrom`	chromosome of region to be plotted
`chromstart`	start position
`chromend`	end position
`type`	type of plot ('region','circles','density')
`colorby`	vector to scale colors by
`colorbycol`	palette to apply color scale to (only valid when colorby is not NULL)
`colorbyrange`	the range of values to apply the color scale to. Values outside that range will be set to the limits of the range.
`rownumber`	vector giving the row numbers of each bed element to be plotted.
`row`	How row number should be determined. Appropriate values are 'auto' or 'supplied'
`height`	Value, typically between 0 and 1, that sets the height of each bed element
`plotbg`	The background color of the plot
`wiggle`	the fraction of the plot to leave blank on either side of each element to avoid overcrowding.
`splitstrand`	TRUE/FALSE indicating whether reverse strnad bed elements shold be plotted below the x axis. (only valid when row is set to 'auto')
`numbins`	The number of bins to divide the region into when type is set to density (only valid when type is set to 'density')
`binsmoothing`	umber of bins to sum together when type is set to density (only valid when type is set to 'density')
`palettes`	list of color palettes used for density plots. Each row can have a unique palette. number of palettes is less than the number of rows then only the first palette is used (only valid when type is set to 'density')
`rowlabels`	labels for the y-axis
`rowlabelcol`	color of the y-axis labels
`rowlabelfont`	font of the y-axis labels
`rowlabelcex`	font size of the y-axis labels
`maxrows`	The maximum number of rows to plot on the y-axis
`color`	single color or vector of colors to use to plot the points or regions (not valid when type is set to 'density')
`xaxt`	A character which specifies the x axis type. See `par`
`yaxt`	A character which specifies the y axis type. See `par`
`xlab`	Label for the x-axis
`ylab`	Label for the y-axis
`xaxs`	Must be set to 'i' for appropriate integration into Sushi plots. See `par`
`yaxs`	Must be set to 'i' for appropriate integration into Sushi plots. See `par`
`bty`	A character string which determined the type of box which is drawn about plots. See `par`
`border`	border color drawn around each bed element or density bin. Set to 'n' for none.
`...`	values to be passed to other functions
