In tseries: Time Series Analysis and Computational Finance

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.

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.

Value

None.

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)
