geneplotter contains plotting functions for microarrays To Do: o A mechanism to order the rows and columns of the microarray matrix. order.restricted is a start. We need a mechanism for dendrograms. Dan Carr suggested that there was a method based on Principle components. o Links to the annotation library. Using locator(1) we should be able to simulate interaction with the plot and look up genes at LocusLink etc. o Color scheme for Red-Blue is the same as Cheng's but the Red Green still looks funny. o Need some notion of a viewport so that we can zoom in and out. Perhaps Paul Murrell, Ross Ihaka or Saikat DebRoy can help out in this regard. o Lots of other visualization methods need to be implemented.
