Hello! Happy Thanksgiving to those who are celebrating. I have a zoo series that I am plotting, and I would like to have some vertical lines at certain points, to indicate US business cycles. Here is an example: app1 <- get.hist.quote(instrument="appl", start="1985-01-01",end="2016-08-31", quote="AdjClose", compression="m") #Fine plot(app1,main="Historical Stock Prices: Apple Corporation") #Still Fine #Now I want to use abline at July 1990 and March 1991 (as a start) for business cycles. I tried v=67 and v="1990-07", no good. I have a feeling that it's really simple and I'm just not seeing it. Any help much appreciated. Thanks, Erin -- Erin Hodgess Associate Professor Department of Mathematical and Statistics University of Houston - Downtown mailto: erinm.hodgess at gmail.com [[alternative HTML version deleted]]
Hi Erin,
I would look at:
par("usr")
to see what the range of the abscissa might be.

Recessions are typically shown by shading. The zoo package has xblocks for this purpose. If app1 is your zoo object then: plot(app1) tt <- time(app1) xblocks(tt, tt >= "1990-07-01" & tt <= "1991-03-31", col = rgb(0.7, 0.7, 0.7, 0.5)) # transparent grey See ?xblocks for more info.
