I agree it may not be 100% clear but ?names does say
"The default methods get and set the '"names"' attribute
of a vector or list." and if you issue the command:
methods("names")
you find that the only non-default method is names.dist.

?vector tells me that factors are not vectors, but ?names does not tell me
that names() is only defined for vectors and lists. If it were, how
should I understand the following?
> x <- factor(c("one","three"))
> names(x) <- c("fred","jim")
> names(x)
[1] "fred" "jim"
> class(x)
[1] "factor"
