[BioC] grid.chromosome in quantsmooth, without cytobands?

[Paul Shannon]

I am very keen to use the grid.chromosome function in the bioc package quantsmooth.

I'd like the karyograms to be rendered *without* cytobands -- so that the interior of each idiogram is available for me to plot other data into.

I notice that there is a 'bands' argument to grid.chromosome, with expected value of either 'major' or 'minor'.  Would it be possible to support a third option, 'none'?

Thanks!
