Arguments

m

a matrix

scale

Include a graph scale showing this range of values ‘image’ function

na.color

the color to draw over NA values

...

additional paramters to ‘image’

Details

A small wrapper around the ‘image’ function to display genome region summary statistics. Additional parameters will be passed along to the image function.

The scale argument is a two-element vector that provides a floor and ceiling for the matrix and allows a crude scale bar to be included on the lower potion of the graph.

For other colors consider using the geneplotter (dChip.colors) or marrayPlots (maPalette) library functions (i.e. regmap(m, col=dChipColors(50)))
