plot.fbroc.perf: Plots ROC based performance metric as histogram
Description
Given an object of class fbroc.perf this function plots the results of
the bootstrap as a histogram. The confidence interval is also included by
default.
Usage
## S3 method for class 'fbroc.perf':
plot(x, bins = NULL, col = "white",
fill = "lightblue", print.plot = TRUE, show.conf = TRUE,
conf.text = TRUE, ...)
Arguments
x
Object of class fbroc.perf to be plotted.
bins
Number of bins for histogram. Default value depends on the number of bootstrap
values and the number of unique bootstrap performance values.
col
Color of outline of histogram bars. Defaults to white.
fill
Fill of histogram bars. Defaults to lightblue.
print.plot
Logical specifying whether the plot should be printed.
show.conf
Logical specifying whether the confidence interval
should be displayed.
conf.text
Logical specifying whether the confidence interval limits
should also be displayed as text.
...
Further arguments passed to or from other methods.
Value
A ggplot, so that the user can customize the plot further.
y <- rep(c(TRUE, FALSE), each = 500)
x <- rnorm(1000) + y
result.boot <- boot.roc(x, y, n.boot = 1000)
result.perf <- perf(result.boot, "auc")
plot(result.perf)
