[R] R2WinBugs problem

[Mark Irwin]

I'm having difficulty running R2WinBugs on a setup that previously 
worked for me (Dell Laptop, Windows XP service pack 3, R 2.11.1, WinBugs 
1.43) .  When I issue the following command

  smds.sim <- bugs (data, inits, parameters, "SMDSbrandLoc2.bug",
  debug = T,
  n.thin = n.thin,
  n.chains = n.chains,
  n.burnin = n.burnin,
  n.iter = n.iter)

I get the following error in R

    Error in while (.regexpr("\r", info) > 0) { : argument is of length zero

Also in WinBugs I get the following messages

   dic.set()
   command #Bugs:dic.set cannot be executed (is greyed out)
   update(5)
   coda(*,C:/DOCUME~1/irwin/LOCALS~1/Temp/RtmpOwZetY/coda)
   command #Bugs:coda cannot be executed (is greyed out)
   stats(*)
   command #Bugs:stats cannot be executed (is greyed out)
   dic.stats()

   DIC
   history(*,C:/DOCUME~1/irwin/LOCALS~1/Temp/RtmpOwZetY/history.odc)
   command #Bugs:history cannot be executed (is greyed out)

I am able to run the analysis on a Mac under Parallel Desktop (XP 
Service Pack 3, R 2.11.1, WinBugs 1.43) and on an Amazon Cloud Machine 
(R 2.11.1, WinBugs 1.43, not sure which version of Windows).

Does anybody have any idea what might be causing that error?  An even 
better, an idea how to fix it?

Mark
