ib.plot.bcea {BCEA}  R Documentation 
Plots the distribution of the Incremental Benefit (IB) for a given value of the willingness to pay threshold.
## S3 method for class 'bcea' ib.plot( he, comparison = NULL, wtp = 25000, bw = "bcv", n = 512, xlim = NULL, graph = c("base", "ggplot2"), ... ) ib.plot(he, ...)
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 bandwidth 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 xaxis. 
graph 
A string used to select the graphical engine to use for
plotting. Should (partial) match the two options 
... 
Additional arguments 
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 (i.e. when the reference is more costeffective than the comparator).
