Re: [R] abline with zoo series

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.

#Try this:

abline( v= as.Date("1990-07-01") )

The x-axis is being created using the Date class values and formatting.

Hi Erin,
I would look at:

par("usr")

to see what the range of the abscissa might be.
