In riskRegression: Risk Regression Models and Prediction Scores for Survival Analysis with Competing Risks

ggplot AUC curve

Description

ggplot AUC curves

Usage

## S3 method for class 'Score'
autoplot(
  object,
  models,
  type = "score",
  lwd = 2,
  xlim,
  ylim,
  axes = TRUE,
  conf.int = FALSE,
  ...
)

Arguments

object	Object obtained with Score.list
models	Choice of models to plot
type	Character. Either "score" to show AUC or "contrasts" to show differences between AUC.
lwd	Line width
xlim	Limits for x-axis
ylim	Limits for y-axis
axes	Logical. If TRUE draw axes.
conf.int	Logical. If TRUE draw confidence shadows.
...	Not yet used

Examples

library(survival)
library(ggplot2)
set.seed(10)
d=sampleData(100,outcome="survival")
nd=sampleData(100,outcome="survival")
f1=coxph(Surv(time,event)~X1+X6+X8,data=d,x=TRUE,y=TRUE)
f2=coxph(Surv(time,event)~X2+X5+X9,data=d,x=TRUE,y=TRUE)
xx=Score(list(f1,f2), formula=Surv(time,event)~1,
data=nd, metrics="auc", null.model=FALSE, times=seq(3:10))
g <- autoplot(xx)
print(g)
aucgraph <- plotAUC(xx)
plotAUC(xx,conf.int=TRUE)
plotAUC(xx,which="contrasts")
plotAUC(xx,which="contrasts",conf.int=TRUE)
