Duncan, Very nice tutorial. However it does NOT take away from the fact that _very_ simple_ scripts (like the one posted by Sun at the beginning of this thread) simply _fail_ in error under Rscript.
Whereas they don't under R or r. The R environment ships an interpreter meant for command-line and scripting use which fails on simple scripts that happen to use S4. But I am tired of arguing for reversing this as I have gotten nowhere in all those years.
