I´ve tried version 1.9.0 barplot with these (and others) example from the help page: tN <- table(Ni <- rpois(100, lambda=5)) r <- barplot(tN, col='gray') I get : <<...OLE_Obj...>> Same example with version 1.8.1 gives the following result: <<...OLE_Obj...>> What is wrong with v.1.9.0? Thanks, Carlos Guevel
