plot_evpi: Plot of Expected Value of Perfect Information (EVPI)

In DARTH-git/darthtools: darthtools is an R package that contains tools developed by the Decision Analysis in R for Technologies in Health (DARTH) workgroup to construct model-based cost-effectiveness analysis in R.

Plot of Expected Value of Perfect Information (EVPI)

Description

Plots the evpi object created by calc_evpi.

Usage

plot_evpi(
  x,
  txtsize = 12,
  currency = "$",
  effect_units = "QALY",
  n_y_ticks = 8,
  n_x_ticks = 20,
  xbreaks = NULL,
  ybreaks = NULL,
  xlim = c(0, NA),
  ylim = NULL,
  ...
)

Arguments

x	object of class evpi, produced by function calc_evpi
txtsize	base text size
currency	string with currency used in the cost-effectiveness analysis (CEA). Default: $, but it could be any currency symbol or word (e.g., £, €, peso)
effect_units	units of effectiveness. Default: QALY
n_x_ticks, n_y_ticks	number of axis ticks
xbreaks, ybreaks	vector of axis breaks. will override n_x_ticks and/or n_y_ticks if provided.
xlim, ylim	vector of axis limits, or NULL, which sets limits automatically
...	further arguments to plot. This is not used by dampack but required for generic consistency.

Value

A ggplot2 plot with the EVPI
