plot.incremental: Plot of incremental performance

Description

Represents prediction performances upon sequential inclusion of the predictors in a logistic or Cox regression model as produced by Incremental. The median and quantiles of the performance metric are reported. See examples in Incremental.

Usage

# S3 method for incremental
plot(
  x,
  quantiles = c(0.05, 0.95),
  col = c("red", "grey"),
  col.axis = NULL,
  xgrid = FALSE,
  ygrid = FALSE,
  output_data = FALSE,
  ...
)
IncrementalPlot(
  x,
  quantiles = c(0.05, 0.95),
  col = c("red", "grey"),
  col.axis = NULL,
  xgrid = FALSE,
  ygrid = FALSE,
  output_data = FALSE,
  ...
)
PlotIncremental(
  x,
  quantiles = c(0.05, 0.95),
  col = c("red", "grey"),
  col.axis = NULL,
  xgrid = FALSE,
  ygrid = FALSE,
  output_data = FALSE,
  ...
)

Value

A plot.
