[R] How can I draw bars

[Steven McKinney]

Hi Raymond,

You might be able to get the plots you want
with the 'cytoband' material provided in
the Bioconductor package "SNPchip".

Check out the SNPchip data set 'cytoband'
and the plot function "plotCytoband"
for ideas.  This material is used e.g.
in Bioconductor package "VanillaICE"
to add a chromosome graphic to the
bottom of data plots of genomic data.
You can see examples in the vignette
PDFs.
