The standard forecast-round chart pack

Source: R/chart_pack.R
chart_pack.Rd

Produces the chart set a forecast round is discussed from: the forecast fans, the filtered latent states, the historical shock decomposition of inflation, and the model's monetary transmission. Output is a multi-page PDF by default, or numbered PNGs.

Usage

chart_pack(
  round,
  file = NULL,
  charts = NULL,
  vars = NULL,
  width = 9,
  height = 6.5
)

Arguments

round

A qpm_round.

file

Output file. A .pdf extension gives one multi-page document; a .png extension gives numbered files (name-1.png, ...). NULL draws to the current device.

charts

Which charts to include, from "forecast", "gaps", "decomposition", "transmission". Default: all four.

vars

Variables for the forecast page. Default: the model's headline set, whichever of pi4/pi, i, y_gap, q exist.

width, height

Page size in inches.

Value

The output path (invisibly), or NULL when drawing to the current device.

Examples

m <- qpm_template("bkl")
obs <- simulate(qpm_solve(m), nsim = 40, seed = 1, burn = 20)
obs$period <- next_quarters("2016-Q1", 40)
r <- qpm_round("demo", m, obs[, c("period", "pi", "i", "q")], horizon = 8)
pdf_path <- file.path(tempdir(), "pack.pdf")
chart_pack(r, pdf_path)
