plot.xts with Moving Average Panel

(for all plot.xts posts, see http://timelyportfolio.blogspot.com/search/label/plot.xts)

As another example of all that we can do with the new plot.xts, let’s try to do a price plot with a moving average overlays.  We will use the ETFs shown by Mebane Faber at http://www.mebanefaber.com/timing-model/.  With the panel functionality, it is very easy to specify a panel to draw the price line and then add the calculated moving average.  Notice how in all the examples, the recession block appears easily and very nicely.

Also, if you wanted to specify some funky layouts, we have that option.  For this case, I do not think it makes much sense, but in the future I will demonstrate some more appropriate uses.

Or as one more example, let’s change it up just slightly.
