##### Plot Two Time Series

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)
```
