Plotting Time-Series Objects
Plotting method for objects inheriting from class "ts"
.
Usage
## S3 method for class 'ts':
plot(x, y = NULL, plot.type = c("multiple", "single"),
xy.labels, xy.lines, panel = lines, nc, yax.flip = FALSE,
mar.multi = c(0, 5.1, 0, if(yax.flip) 5.1 else 2.1),
oma.multi = c(6, 0, 5, 0), axes = TRUE, ...)## S3 method for class 'ts':
lines(x, \dots)
Arguments
- x, y
- time series objects, usually inheriting from class
"ts"
. - plot.type
- for multivariate time series, should the series by plotted separately (with a common time axis) or on a single plot? Can be abbreviated.
- xy.labels
- logical, indicating if
text()
labels should be used for an x-y plot, or character, supplying a vector of labels to be used. The default is to label for up to 150 points, and not for more. - xy.lines
- logical, indicating if
lines
should be drawn for an x-y plot. Defaults to the value ofxy.labels
if that is logical, otherwise toTRUE
. - panel
- a
function(x, col, bg, pch, type, ...)
which gives the action to be carried out in each panel of the display forplot.type = "multiple"
. The default islines
. - nc
- the number of columns to use when
type = "multiple"
. Defaults to 1 for up to 4 series, otherwise to 2. - yax.flip
- logical indicating if the y-axis (ticks and numbering)
should flip from side 2 (left) to 4 (right) from series to series
when
type = "multiple"
. - mar.multi, oma.multi
- the (default)
par
settings forplot.type = "multiple"
. Modify with care! - axes
- logical indicating if x- and y- axes should be drawn.
- ...
- additional graphical arguments, see
plot
,plot.default
andpar
.
Details
If y
is missing, this function creates a time series
plot, for multivariate series of one of two kinds depending on
plot.type
.
If y
is present, both x
and y
must be univariate,
and a scatter plot y ~ x
will be drawn, enhanced by
using text
if xy.labels
is
TRUE
or character
, and lines
if
xy.lines
is TRUE
.

functionality.
Examples
library(stats)
require(graphics)
## Multivariate
z <- ts(matrix(rt(200 * 8, df = 3), 200, 8),
start = c(1961, 1), frequency = 12)
plot(z, yax.flip = TRUE)
plot(z, axes = FALSE, ann = FALSE, frame.plot = TRUE,
mar.multi = c(0,0,0,0), oma.multi = c(1,1,5,1))
title("plot(ts(..), axes=FALSE, ann=FALSE, frame.plot=TRUE, mar..., oma...)")
z <- window(z[,1:3], end = c(1969,12))
plot(z, type = "b") # multiple
plot(z, plot.type = "single", lty = 1:3, col = 4:2)
## A phase plot:
plot(nhtemp, lag(nhtemp, 1), cex = .8, col = "blue",
main = "Lag plot of New Haven temperatures")
## xy.lines and xy.labels are FALSE for large series:
plot(lag(sunspots, 1), sunspots, pch = ".")
SMI <- EuStockMarkets[, "SMI"]
plot(lag(SMI, 1), SMI, pch = ".")
plot(lag(SMI, 20), SMI, pch = ".", log = "xy",
main = "4 weeks lagged SMI stocks -- log scale", xy.lines = TRUE)
