Hi Gang:

I didn't know if you had seen this.  It sounds like it might be interesting.

Dear BUGS users,

 
 I have written a R function to store the MCMC simulations produced by 
WinBUGS in a R list. The code is available from here: 
http://forums.cirad.fr/logiciel-R/viewtopic.php?t=1749
 
 I have nothing to gain from sharing this code - just hope this could help.
 
Below are some explanations:
 
  By default, the R function  bugs()  from the R2WinBUGS package, 1) 
runs WinBUGS, 2) stores simulations in R, 3) produces summary statistics 
on simulations.
 
 The  bugs()  function could crash whereas WinBUGS works well. Or one 
could be interested only in running WinBUGS and storing the simulations; 
this could be achieved with option codaPkg=TRUE in the bugs() function 
and then applying the  read.bugs()  function for further output analysis 
using the coda package.
  
 The function  read.winbugs()  given in the document allows a more 
straightforward storing of the simulations in a R list, and this list 
allows a particularly easy access to the simulations, nice for further 
'bare-hand' treatment of the simulations.
 
 Of course it is also possible to use both an available R function as 
well as my function  read.winbugs()  to get this friendly list.
 
 
 Hope this could help,
  
                           Stéphane
