Dear r-devel members,
It's just been brought to my attention that R permits non-unique column
names in data frames -- e.g., via assignment to names() or colnames(). This
behaviour is consistent with the help files (as I discovered), but it's not
consistent with the behaviour of rownames() and row.

extractor "$" when using contributed packages. For instance:
