Plotting zoo Objects
Plotting method for objects of class
## S3 method for class 'zoo': plot(x, plot.type = c("multiple", "single"), panel = lines, xlab = "Index", ylab = NULL, main = NULL, ylim = NULL, oma = c(6, 0, 5, 0), col = 1, lty = 1, pch = 1, type = "l", nc, ...) ## S3 method for class 'zoo': lines(x, type = "l", \dots)
- an object of class
- for multivariate zoo objects, "multiple" plots the series on multiple plots and "single" superimposes them on a single plot
function(x, y, col, lty, ...)which gives the action to be carried out in each panel of the display for
plot.type = "multiple".
- xlab, ylab, main, ylim, oma
- graphical arguments, see
- col, lty, pch, type
- graphical arguments that can be vectors or (named) lists. See the details for more information.
- the number of columns to use when
plot.type = "multiple". Defaults to
1for up to
4series, otherwise to
- additional graphical arguments.
The methods for
lines are very similar
to the corresponding
ts methods. However, the handling of
lty is more
flexible for multivariate series. These parameters can be
vectors of the same length as the number of series plotted or
are recycled if shorter. They can also be (partially) named list, e.g.,
list(A = c(1,2), c(3,4)) in which
c(3, 4) is the
default value and
c(1, 2) the value only for series
Also see the examples.

This does NOT dispatch plot.zoo. plot(coredata(merge(x, x2)))
