plot.PosteriorIR {bsvars}

Plots impulse responses

Description

Plots of of all variables to all shocks including their median and percentiles.

Usage

## S3 method for class 'PosteriorIR'
plot(
  x,
  probability = 0.9,
  col = "#ff69b4",
  main,
  xlab,
  mar.multi = c(1, 4.1, 0, 1.1),
  oma.multi = c(6, 0, 5, 0),
  ...
)

Arguments

x

an object of class PosteriorIR obtained using the compute_impulse_responses() function containing posterior draws of impulse responses.

probability

a parameter determining the interval to be plotted. The interval stretches from the 0.5 * (1 - probability) to 1 - 0.5 * (1 - probability) percentile of the posterior distribution.

col

a colour of the plot line and the ribbon

main

an alternative main title for the plot

xlab

an alternative x-axis label for the plot

mar.multi

the default mar argument setting in graphics::par. Modify with care!

oma.multi

the default oma argument setting in graphics::par. Modify with care!

...

additional arguments affecting the summary produced.
