Hi Jeff,
  Did you make any progress? There were some minor glitches in the
  devel version of geneplotter (that have now been repaired) so that
  the  byChroms HowTo should once again be available. This document
  details the steps needed to construct the basic object you need to 
  use the geneplotter package.


  should give you an menu, from that you can select the byChrom
  vignette (on windows this should appear in the menu bar but that is
  slightly broken -- look for a new R release in the next few days),

  You can also extract the code from the vignette by using tangleToR
  (also in the DynDoc package), and of course there is always
  vExplorer for a more interactive tool for looking at the code,
  (it is in the package tkWidgets),

  please let me know if you need more details
