plot.surv_model_performance_rocs function

Plot ROC Curves for Survival Models

This function plots objects of class "surv_model_performance_rocs" - ROC curves for specific time points for survival models created using the model_performance(..., type="roc").

## S3 method for class 'surv_model_performance_rocs'
plot(
  x,
  ...,
  title = "ROC curves for selected time points",
  subtitle = "default",
  auc = TRUE,
  colors = NULL,
  facet_ncol = NULL
)

Arguments

• x: an object of class "surv_model_performance_rocs" to be plotted
• ...: additional objects of class "surv_model_performance_rocs" to be plotted together
• title: character, title of the plot
• subtitle: character, subtitle of the plot, 'default' automatically generates "created for XXX, YYY models", where XXX and YYY are the explainer labels
• auc: boolean, whether the AUC values should be plotted
• colors: character vector containing the colors to be used for plotting variables (containing either hex codes "#FF69B4", or names "blue")
• facet_ncol: number of columns for arranging subplots

Returns

An object of the class ggplot.

Examples

library(survival)
library(survex)

model <- randomForestSRC::rfsrc(Surv(time, status) ~ ., data = veteran)
exp <- explain(model)

m_perf_roc <- model_performance(exp, type = "roc", times = c(100, 300))
plot(m_perf_roc)
