plot.Arima | R Documentation |
Produces a plot of the inverse AR and MA roots of an ARIMA model. Inverse roots outside the unit circle are shown in red.
## S3 method for class 'Arima'
plot(
x,
type = c("both", "ar", "ma"),
main,
xlab = "Real",
ylab = "Imaginary",
...
)
## S3 method for class 'ar'
plot(x, main, xlab = "Real", ylab = "Imaginary", ...)
## S3 method for class 'Arima'
autoplot(object, type = c("both", "ar", "ma"), ...)
## S3 method for class 'ar'
autoplot(object, ...)
x |
Object of class “Arima” or “ar”. |
type |
Determines if both AR and MA roots are plotted, of if just one set is plotted. |
main |
Main title. Default is "Inverse AR roots" or "Inverse MA roots". |
xlab |
X-axis label. |
ylab |
Y-axis label. |
... |
Other plotting parameters passed to |
object |
Object of class “Arima” or “ar”. Used for ggplot graphics (S3 method consistency). |
