eib.plot(he, comparison=NULL, pos=c(1,0), size=NULL, plot.cri = NULL, graph=c("base","ggplot2"), ...)bcea object containing the results of the Bayesian modelling and the economic
evaluation.
NULL plots all the comparisons together. Any subset of the possible
comparisons can be selected (e.g., comparison=c(1,3) or comparison=2).
(bottom|top)(right|left)
for base graphics and bottom|top|left|right for ggplot2. It can be a
two-elements vector, which specifies the relative position on the x and y axis
respectively, or alternatively it can be in form of a logical variable, with
FALSE indicating to use the default position and TRUE to place it
on the bottom of the plot. Default value is c(1,0), that is the bottomright
corner inside the plot area.
graph="ggplot2", otherwise it will be ignored with a message. If set to
NA, the break-even point line(s) and label(s) are suppressed, with both base
graphics and ggplot2.
NULL draws the 95% credible intervals if
only one comparison is selected, and does not include them for multiple comparisons.
Setting plot.cri=TRUE or plot.cri=FALSE forces the function to add
the intervals or not. The level of the intervals can be also set, see ... for more
details.
"base" or "ggplot2". Default value is "base".
graph="ggplot2" and a named theme object is supplied, it will be added to
the ggplot object. If plot.cri=TRUE the level of the interval can be set using
the argument alpha, with default at alpha=0.05. Additionally the method
of calculation of the credible intervals can be chosen with the option
cri.quantile: the default value TRUE indicates that the credible intervals
are defined as the interval between the alpha/2-th and 1-alpha/2-th
quantiles of the IB distribution. Setting cri.quantile=FALSE will use a
normal approximation on the IB distribution to calculate the intervals.
