Artimon,
It seems that you have got the data wrong: The data structure is a list of 4
characters:
> list("y","X","n","m")
[[1]]
[1] "y"
[[2]]
[1] "X"
[[3]]
[1] "n"
[[4]]
[1] "m"
And that is hardly what you want, presumably you meant
list("y"=y,"X"=X,"n"=n,"m"=m)
??

- Your example is not reproducible for us (without the data).
- Is WinBUGS runnign correctly (see its output with debug=TRUE)?
- What does traceback() tell us?
Which versions of R, WinBUGS and R2WinBUGS are in use?
