Adding colored background area to a time series plot
...on and example given here:
http://www.mail-archive.com/r-help at stat.math.ethz.ch/msg73948.html

My problem/difference is that my time series looks like so:
> library(quantmod)
> getSymbols("^GSPC", from="2008-01-01")
> xtsPR <- diff(log(Ad(GSPC)))
> head(xtsPR)
GSPC.Adjusted
2008-01-02 NA
2008-01-03 0.000000000
2008-01-04 -0.024857950
2008-01-07 0.003218041
2008-01-08 -0.018522677
2008-01-09 0.013532064
So my dates along the x-axis are in the format "2008-01-02"...
