plot.AROC {AROC}R Documentation

Default AROC plotting

Description

Takes a fitted AROC object produced by AROC.bnp(), AROC.bsp(), AROC.sp(), AROC.kernel(), pooledROC.BB() or pooledROC.emp() and plots the covariate-adjusted ROC curve (AROC) and associated area under the AROC (AAUC); or the pooled ROC curve and associated AUC.

Usage

## S3 method for class 'AROC'
plot(x, ...)

Arguments

x

an object of class AROC as produced by AROC.bnp(), AROC.bsp(), AROC.sp(), AROC.kernel(), pooledROC.BB() or pooledROC.emp()

...

further arguments passed to or from other methods

Examples

library(AROC)
data(psa)
# Select the last measurement
newpsa <- psa[!duplicated(psa$id, fromLast = TRUE),]

# Log-transform the biomarker
newpsa$l_marker1 <- log(newpsa$marker1)

m0 <- AROC.bnp(formula.healthy = l_marker1 ~ f(age, K = 0),
group = "status", tag.healthy = 0, data = newpsa, scale = TRUE,
p = seq(0,1,l=101), compute.lpml = TRUE, compute.WAIC = TRUE,
a = 2, b = 0.5, L = 10, nsim = 5000, nburn = 1000)

plot(m0)
