How can I shade the background area of a zoo time series object between specific dates?
Dear list members, How can I shade the background area of a zoo time series object between specific dates? eg. library(tseries) library(zoo) SP500<-get.hist.quote("^GSPC", start = "1990-01-01", quote = "Close") plot(SP500) How can I produce the same plot but with a (say) red background between 2007-04-12 and 2008-05-14 ?

forecast & xreg
Dear all, I am fitting an arimax (arima with some extra explanatory variables) model to a time series. Say, I have a Y (dependent variable) and an X (explanatory).
