I have what may be a simple/foolish question, but I've done the due diligence and looked through pages of posts here as well as several of the PDFs on the CRAN site, but haven't been able find what I'm after.
I am working with a list of say 3 histogram objects A, B & C, and each histogram is a list of 7 elements. I would like to access $name, the 6th element, of histograms A,B and C. Trial and error yielded some results that told me I clearly don't understand how R interprets index commands. For the histogram list above: a[1:2] give histograms A and B as expected. a[[1:2]] gives the second element of histogram 1, but a[[1:1]] gives all elements of histogram 1, while a[[1:3]] gives null?! If anyone could help with an explanation of indexing rules, or a source that does so, I would very much appreciate it. Oh and an answer to the first question!
