   Dear Ben,

   Thank you very much for your reply to my R2WinBUGS query.  As requested, I
   am attaching the following files to this e-mail:

   1) The .odc file containing the WinBUGS code I am trying to run from R.  The
   nodes to be monitored for posterior inference are: T, best, d, lor, mu, or
   and p.

   2) The .R file containing the call to the bugs() function in the package

   3)  The .bug file containing the model specification used when calling
   Please  note  that  I  have tried to specify the initial values of the
   parameters  using a list rather than a function (as suggested by Peter
   Alspach), and got the following error message:

   Error in bugs(data, inits, model.file = "model.bug", parameters = c("T",  :
     Number of initialized chains (length(inits)) != n.chains

   Many thanks for any insight you may be able to provide into why the call to
   R2WinBUGS breaks down.  In case this may be needed, I am using R 2.6.2 and
   WinBUGS 1.4.

   Kind regards,
