fanchart {vars}R Documentation

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.
