fanchart: Fanchart plot for objects of class varprd

In vars: VAR Modelling

Fanchart plot for objects of class varprd

Description

Time Series plots of VAR forecasts with differently shaded confidence regions (fanchart) for each endogenous variable.

Usage

fanchart(x, colors = NULL, cis = NULL, names = NULL, main = NULL, ylab =
NULL, xlab = NULL, col.y = NULL, nc, plot.type = c("multiple",
"single"), mar = par("mar"), oma = par("oma"), ... )

Arguments

x	An object of class ‘varprd’; generated by predict().
colors	Character vector of colors to be used for shading. If unset, a gray color scheme is used.
cis	A numeric vector of confidence intervals. If unset the sequence from 0.1 to 0.9 is used (step size 0.1).
names	Character vector, names of variables for fancharts. If unset, all variables are plotted.
main	Character vector, title for fanchart plots.
ylab	Character, ylab for fanchart.
xlab	Character, xlab for fanchart.
col.y	Character, color for plotted time series.
plot.type	Character, if multiple all fancharts appear in one device.
nc	Integer, number of columns if plot.type is multiple.
mar	Vector, setting of margins.
oma	Vector, setting of outer margins.
...	Dot argument, passed to plot.ts.
