seqplot.ts: Plot Two Time Series

Description

Plot two time series on the same plot frame.

Usage

seqplot.ts(x, y, colx = "black", coly = "red", typex = "l",
           typey = "l", pchx = 1, pchy = 1, ltyx = "solid",
           ltyy = "solid", oma = c(6, 0, 5, 0), ann = par("ann"),
           xlab = "Time", ylab = deparse(substitute(x)), main = NULL)

Arguments

x, y

the time series.

colx, coly

color code or name for the x and y series, see colors, palette.

typex, typey

what type of plot should be drawn for the x and y series, see plot.

pchx, pchy

character or integer code for kind of points/lines for the x and y series.

ltyx, ltyy

line type code for the x and y series, see lines.

oma

a vector giving the size of the outer margins in lines of text, see par.

ann

annotate the plots? See par.

xlab, ylab

titles for the x and y axis.

main

an overall title for the plot.

Value

• None.

Details

Unlike plot.ts the series can have different time bases, but they should have the same frequency. Unlike ts.plot the series can be plotted in different styles and for multivariate x and y the common variables are plotted together in a separate array element.

Examples

data(USeconomic)
x <- ts.union(log(M1), log(GNP), rs, rl)
m.ar <- ar(x, method = "ols", order.max = 5)
y <- predict(m.ar, x, n.ahead = 200, se.fit = FALSE)
seqplot.ts(x, y)
