Plotting the incremental cost-effectiveness plane.
plot_ice.Rd
This function plots the incremental cost-effectiveness plane.
Arguments
- df
a dataframe.
- e_int
character. Name of variable of the dataframe containing total effects of the intervention strategy.
- e_comp
character. Name of variable of the dataframe containing total effects of the comparator strategy.
- c_int
character. Name of variable of the dataframe containing total costs of the intervention strategy.
- c_comp
character. Name of variable of the dataframe containing total costs of the comparator strategy.
- col
character. Name of variable of the dataframe to use to colour (in blue) the plotted dots. Default is NULL which results in grey dots.
- n_it
(vector of) numeric value(s). Designate which iteration should be coloured in the colour red.
- wtp
numeric. Default is NULL. If different than NULL, plots a linear line with intercept 0 and the defined slope.
