If you are willing to do it yourself you can define a class for which indexing behaves that way.
I'd like to prefix all these solutions with "Here's how to do it, but don't actually do it you crazy fool". It's on a par with redefining pi, or redefining '+'. And then redefining '<-'.
These techniques have their proper place, and that would be in the currently non-existent obfuscated R contest.
No, the R-ish (iRish?) way is to index vectors from 1. That's what the R gods intended!
