Ah... of course. I had read the vignette for xts, but didn't notice the indexing capabilities. Thank you. > ded below converts the index values to > a specific year.

You mentioned "month-free" solution being similar, but I am not sure about that part. Specifically, one thing I want to do is compare data by month, but I also want to see that comparison preserve the day of the week. For example, 2011/10/01 is a Saturday, but 2010/10/01 is a Friday. When I see both on the same plot, I want to see them lined up by days of week, rather than have the first day for each at the same place on the graph. (I'm not sure I'm communicating this well, I hope this is making sense).
