ib.plot {BCEA} | R Documentation |
Plots the distribution of the Incremental Benefit (IB) for a given value of the willingness to pay threshold
ib.plot(he, comparison = NULL, wtp = 25000, bw = nbw, n = 512, xlim = NULL, graph=c("base","ggplot2"))
he |
A |
comparison |
In the case of multiple interventions, specifies the one to be used in comparison with
the reference. Default value of |
wtp |
The value of the willingness to pay threshold. Default value at |
bw |
Identifies the smoothing bandwith used to construct the kernel estimation of the IB density. |
n |
The number of equally spaced points at which the density is to be estimated. |
xlim |
The limits of the plot on the x-axis. |
graph |
A string used to select the graphical engine to use for plotting. Should (partial-)match
the two options |
ib |
A ggplot object containing the requested plot. Returned only if |
The function produces a plot of the distribution of the Incremental Benefit for a given value of the willingness to pay parameter. The dashed area indicates the positive part of the distribution (ie when the reference is more cost-effective than the comparator).
