contour.bcea {BCEA}  R Documentation 
bcea
Produces a scatterplot of the costeffectiveness plane, with a contourplot of the bivariate density of the differentials of cost (yaxis) and effectiveness (xaxis)
## S3 method for class 'bcea' contour(x, comparison = 1, scale = 0.5, nlevels = 4, levels = NULL, pos = c(1,0), xlim=NULL, ylim=NULL, graph=c("base","ggplot2"), ...)
x 
A 
comparison 
In case of more than 2 interventions being analysed, selects which plot should be made.
By default the first comparison among the possible ones will be plotted. If

scale 
Scales the plot as a function of the observed standard deviation. 
levels 
Numeric vector of levels at which to draw contour lines. Will be ignored using

nlevels 
Number of levels to be plotted in the contour. 
pos 
Parameter to set the position of the legend. Can be given in form of a string

graph 
A string used to select the graphical engine to use for plotting. Should (partial)match
the two options 
xlim 
The range of the plot along the xaxis. If NULL (default) it is determined
by the range of the simulated values for 
ylim 
The range of the plot along the yaxis. If NULL (default) it is determined
by the range of the simulated values for 
... 
Additional arguments to 'plot.window', 'title', 'Axis' and 'box', typically graphical
parameters such as 'cex.axis'. Will be ignored if 
ceplane 
A ggplot object containing the plot. Returned only if 
Plots the costeffectiveness plane with a scatterplot of all the simulated values from the (posterior) bivariate distribution of (Delta_e,Delta_c), the differentials of effectiveness and costs; superimposes a contour of the distribution and prints the estimated value of the probability of each quadrant (combination of positive/negative values for both Delta_e and Delta_c)
