NULL, main = NULL, lty = NULL, lwd = NULL, col = NULL, ylim = NULL, ylab
= NULL, xlab = NULL, nc, mar = par("mar"), oma = par("oma"), ...) 
## S3 method for class 'varprd':
plot(x, plot.type = c("multiple", "single"),
names = NULL, main = NULL, col = NULL, lty = NULL, lwd = NULL,
ylim = NULL, ylab = NULL, xlab = NULL, nc, mar = par("mar"),
oma = par("oma"), ...)
## S3 method for class 'varstabil':
plot(x, plot.type = c("multiple", "single"), names =
NULL, main = NULL, nc, mar = par("mar"), oma = par("oma"), ...)

lag.acf2

Integer, lag.max for ACF of squared residuals.

lag.pacf

Integer, lag.max for PACF of residuals.

lag.pacf2

Integer, lag.max for PACF of squared residuals.

legend

Character vector of names in legend.

lty

Integer/Character, the line types.

lty.fit

Vector, lty for diagram of fit.

Details

The plot-method for objects with class attribute vec2var is the same as for objects with class attribute varest. Hence, the same arguments can be utilised.
