Combined plot of a time Series and its autocorrelation and partial autocorrelation

```
PlotACF(series, lag.max = 10 * log10(length(series)), main = NULL, cex = NULL, ...)
PlotGACF(series, lag.max = 10 * log10(length(series)), type = "cor", ylab = NULL, ...)
```

- series
univariate time series.

- lag.max
integer. Defines the number of lags to be displayed. The default is 10 * log10(length(series)).

- main
an overall title for the plot

- cex
numerical value giving the amount by which plotting text and symbols should be magnified relative to the default.

- type
character string giving the type of acf to be computed. Allowed values are

`"cor"`

(the default),`"cov"`

or`"part"`

for autocorrelation, covariance or partial correlation.- ylab
a title for the y axis: see

`title`

.- ...
the dots are passed to the plot command.

PlotACF plots a combination of the time series and its autocorrelation and partial autocorrelation. PlotGACF is used as subfunction to produce the acf- and pacf-plots.
