I'm sure I've read about the difference between a[[i]] and a[i] in R, but I cannot recall what I read. Even more disturbing is the fact that I don't know how to search the newsgroup for this. All the different combinations I tried were declared not to be valid search syntax.
1. What sort of object can the operators [] and [[]] be applied to? How do they differ? I mean objects in standard R, not in packages that provide conceivable overloading of these operators (if that's possible). 2. Meta-question: how could one search for an answer to this question in the newsgroup? 3. Meta-question: how could one search for an answer to this in the FAQ? 4. Meta-question: how could one search for an answer to this in any of the links one is shown after typing help.start()? Thanks for any help.
