As I keep installed `(almost) all released versions of R ever installed on our machines' I can easily run 1.8.1 (or 1.4.x or 1.0.x ...) for you. The only difference between the help page help(tapply) is an extra "require(stats)" statement at the beginning of the `Examples' section in 1.9.0. and the only change to tapply() is group <- rep.int(one, nx)#- to contain the splitting vector instead of group <- rep (one, nx)#- to contain the splitting vector which hardly should have adverse results. In barplot, there's the new 'offset' option --- not in NEWS (!!!!) and another change that may be a problem. Can you dig harder and if possible provide a reproducible (small..) example to make progress here...
