willing2pay: Willingness to pay plot

In henrivanwerkhoven/meta2way: Two-way Meta-Analysis for Cost-Outcome Evaluations

Description

This function allows you to plot a willingness to pay plot based on a two-way meta analysis object.

Usage

willing2pay(object, type, xlim = NA, xlim.quantile = 0.999,
  ylim = 0:1, xlab = "Costs per effect",
  ylab = "Probability of acceptance", main = "Willingness to Pay",
  col = 1, lty = 1, add = FALSE, res = 1000)

Arguments

object	object of class meta2way.
type	character length 1, either 'fixed' or 'random'. If object contains only one type of meta-analysis, this argument can be omitted.
xlim	numeric length 2 with the x-axis limits. Defaults to NA which means the argument xlim.quantile is used to determine xlim.
xlim.quantile	numeric length 1: which upper extreme of costs per effect will be plotted. Defaults to .999. Setting the value to 1 means the most extreme value will be plotted.
ylim	numeric length 2 with the y-axis limits. Defaults to c(0,1)
xlab	character x-axis label. Defaults to 'Costs per effect'
ylab	character y-axis label. Defaults to 'Probability of treshold'
main	character plot title. Defaults to 'Willingness to Pay'
col	line color. Defaults to 1.
lty	line type. Defaults to 1.
add	logical whether to add the line to the previous plot. Defaults to FALSE.
res	integer how many data points should be calculated between xlim[1] and xlim[2]. Defaults to 1000.

Value

Returns NULL invisibly.

Examples

m <- meta2way(study2way(treatments$Abrahams2018.x, treatments$Abrahams2018.y, 'Abrahams 2018'),
              study2way(treatments$Baruch2018.x, treatments$Baruch2018.y, 'Baruch 2018'))
willing2pay(m, 'fixed')
