NEVER, ever, post a question on a new topic in an existing thread - see the posting guide; you pollute the archive, and harm yourself by having your question "disappear". For conversion of SpatialPolygons* objects to read into WinBUGS, see ?sp2WB in the maptools package. Your question is more appropriate for the R-sig-geo list.
