Plotting zoo Objects

Plotting method for objects of class "zoo".

Keywords
ts
Usage
## 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)
Arguments
x
an object of class "zoo".
plot.type
for multivariate zoo objects, "multiple" plots the series on multiple plots and "single" superimposes them on a single plot
panel
a 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 par.
col, lty, pch, type
graphical arguments that can be vectors or (named) lists. See the details for more information.
nc
the number of columns to use when plot.type = "multiple". Defaults to 1 for up to 4 series, otherwise to 2.
...
additional graphical arguments.
Details

The methods for plot and lines are very similar to the corresponding ts methods. However, the handling of graphical parameters col, pch and 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 A. Also see the examples.

Examples
x.Date <- as.Date(paste(2003, 02, c(1, 3, 7, 9, 14), sep = "-"))

## univariate plotting
x <- zoo(rnorm(5), x.Date)
x2 <- zoo(rnorm(5, sd = 0.2), x.Date)
plot(x)
lines(x2, col = 2)

## multivariate plotting
z <- cbind(x, x2, zoo(rnorm(5, sd = 0.5), x.Date))
colnames(z) <- LETTERS[1:3]
plot(z, plot.type = "single", col = list(B = 2))
plot(z, type = "b", pch = 1:3, col = 1:3)
plot(z, type = "b", pch = list(A = 1:5, B = 3), col = list(C = 4, 2))

## plot one zoo series against the other.  This does NOT dispatch plot.zoo.
plot(coredata(merge(x, x2)))
