 I think the problem might be due to naming conventions. Somehow the
 annotation package and cdf packages are called hu6800 but the probe
 package is called hugeneflprobe - I suspect we need to rename it.
 Does anyone know in Biocore know if there is a good reason for this
 naming convention?

 In most cases you are better off using the internal to R mechanisms
 for downloading data packages etc. Those include the functions
 available through the Packages menu on Windows and install.packages2
 in the reposTools package from Bioconductor.

 So something like

 library(reposTools)
 install.packages2("pkgnamehere")

 should work...but in this case it doesn't since hu6800probe does not
 exist.

  Yep, we're going to fix it - thanks for the report.

  And we will send you a properly named version of the 6800 probe
  package if you would be so kind as to tell us your OS (I'm guessing
  Windows since that was the broken link....)
