Something like that, but I think it would be better if it pulled out the
start and end date of the range so that it was clear if it is a list with
named elements or a Date vector. I think that should also be specified in
the text of the doc page. In my case, I needed to split the start and end
as I was passing it on to an existing method that took those two
parameters.
Perhaps you could have the dates feeding into a plot title or something
like that to make the example not too contrived.
