Plotting method for objects inheriting from class "ts".
## 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, ...)
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? |
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 of
xy.labels if that is logical, otherwise to TRUE. |
panel |
a function(x, col, bg, pch, type, ...) which gives the
action to be carried out in each panel of the display for
plot.type="multiple". The default is lines. |
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
for plot.type="multiple". Modify with care! |
axes |
logical indicating if x- and y- axes should be drawn. |
... |
additional graphical arguments, see plot,
plot.default and par. |
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.
ts for basic time series construction and access
functionality.
## 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.mult= c(0,0,0,0), oma.mult= 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, c(nhtemp[-1], NA), cex = .8, col="blue",
main = "Lag plot of New Haven temperatures")
## a clearer way to do this would be
## Not run:
plot(nhtemp, lag(nhtemp, 1), cex = .8, col="blue",
main = "Lag plot of New Haven temperatures")
## End(Not run)
## 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)
