[R] Error in bugs.run -- R2WinBUGS

[Cleber Nogueira Borges]

Hi,

I tried to use MethComp library and this library make use of the WinBUGS 
by R2WinBuGUS,
but I get the follow error in bugs.run:

*Error in bugs.run(n.burnin, bugs.directory, WINE = WINE, useWINE = 
useWINE,  : *
  Look at the log file and
try again with 'debug=TRUE' to figure out what went wrong within Bugs.

Anyone can help-me, please?
Thanks

Cleber
