Plotting cost-effectiveness plane.

This function plots the cost-effectiveness plane for an infinite amount of strategies .

Usage

plot_ce_mult(df, outcomes, costs, ellipse = FALSE, currency = "euro")

Arguments

df

a dataframe.

outcomes

character. Vector of variable names containing the outcomes to be plotted on the x-axis. The variable names should be structured as follows: 't_qaly_d_' followed by the name of the strategy: e.g. 't_qaly_d_intervention'.

costs

character. Vector of variable names containing the costs to be plotted on the y-axis. The variable names should be structured as follows: 't_costs_d_' followed by the name of the strategy: e.g. 't_costs_d_intervention'.

ellipse

logical. Determines whether plot should plot the dots of each iteration (default, ellipse = FALSE), or whether the mean outcomes and costs and their 95procent confidence ellipses should be plotted (TRUE).

currency

character. Default is "euro". Determines the currency sign to use in the incremental cost effectiveness plane. Currently included signs: "euro", "dollar", "yen", "none".

Value

A ggplot2 graph. # Plot cost effectiveness plane as ellipses data("df_pa") df_pa$t_qaly_d_int2 <- df_pa$t_qaly_d_int * 1.5 # creating additional outcome variable df_pa$t_costs_d_int2 <- df_pa$t_costs_d_int * 1.5 # creating additional cost variable plot_ce_mult(df = df_pa, outcomes = c("t_qaly_d_int", "t_qaly_d_comp", "t_qaly_d_int2"), costs = c("t_costs_d_int","t_costs_d_comp", "t_costs_d_int2"), ellipse = TRUE)
