[R] Split charts with ggplot2, tidyquant

[Joshua Ulrich]

If you don't want to wait for a ggplot2 solution, here are two
alternatives you can use right now:

chartSeries(SPYxts)
# or (with xts > 0.10
plot(SPYxts$SPY.Close)
addSeries(SPYxts$SPY.Volume, type = "h")

You might also try autoplot.zoo(), though I've never used it.
