Plot ROC curves — plot

Plot receiver operating characteristics (ROC) curves.

Usage

plot_roc(
  cobraplot,
  title = "",
  stripsize = 15,
  titlecol = "black",
  xaxisrange = c(0, 1),
  yaxisrange = c(0, 1),
  linewidth = 1
)

Arguments

cobraplot: A COBRAPlot object.
title: A character string giving the title of the plot.
stripsize: A numeric value giving the size of the strip text, when the results are stratified by an annotation.
titlecol: A character string giving the color of the title.
xaxisrange: A numeric vector with two elements, giving the lower and upper boundary of the x-axis, respectively.
yaxisrange: A numeric vector with two elements, giving the lower and upper boundary of the y-axis, respectively.
linewidth: The line width used for plotting

Value

Examples

data(cobradata_example)
cobraperf <- calculate_performance(cobradata_example,
                                   binary_truth = "status", aspects = "roc")
#> Warning: Object doesn't have a slot sval. Please run update_cobradata(). For consistency, I will return an empty data.frame
cobraplot <- prepare_data_for_plot(cobraperf, colorscheme = "Dark2",
                                   incltruth = TRUE)
plot_roc(cobraplot)
