How can I change XTS to data.frame and keep Index?

Question

I have an XTS timeseries in R of the following format and am trying to do some processing, subsetting and re-arranging before exporting as a CSV for work in another program.

Answer 1

That's because the dates are rownames in your data.frame. You need to make them a separate column.

Try this:

 data.frame(date=index(master_1), coredata(master_1))
