[R] plotting zoo object

[Gabor Grothendieck]

Please use dput(x) to display data in your posts in easily copied form.

Try this:

library(zoo)
z <- zoo(matrix(1:48, 4, dimnames = list(NULL, month.abb)), 1968:1971)
zz <- zooreg(c(coredata(z)), start = as.yearmon(1968), freq = 12)

You could also consider  using a ts series:

tt <- as.ts(zz)
