plot.evsi: Plot of Expected Value of Sample Information (EVSI)

In DARTH-git/dampack: Decision-Analytic Modeling Package

Plot of Expected Value of Sample Information (EVSI)

Description

Plots the evsi object created by calc_evsi. EVSI is either plotted as a function of additional sample size for each willingness-to-pay threshold provided, or as a function of each willingness-to-pay threshold, depending upon the usage of calc_evsi used to create the evsi object.

Usage

## S3 method for class 'evsi'
plot(
  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,
  col = c("full", "bw"),
  ...
)

Arguments

x	object of class evsi, produced by function calc_evsi
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_y_ticks	number of y-axis ticks
n_x_ticks	number of x-axis ticks
xbreaks	vector of x-axis breaks. will override n_x_ticks if provided.
ybreaks	vector of y-axis breaks. will override n_y_ticks if provided.
xlim	vector of x-axis limits, or NULL, which sets limits automatically
ylim	vector of y-axis limits, or NULL, which sets limits automatically
col	either none, full color, or black and white
...	further arguments to plot. This is not used by dampack but required for generic consistency.

Value

A ggplot2 plot with the EVSI
