plot.zoo {zoo} | R Documentation |
Plotting method for objects of class "zoo"
.
## 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, nc, ...) ## S3 method for class 'zoo': lines(x, type = "l", ...)
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, type |
graphical arguments, see par . |
col, lty, pch |
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. |
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
.
