Default xpose ROC plot function — xplot

Manually generate ROCs from an xpdb object.

Usage

xplot_rocplot(
  xpdb,
  mapping = NULL,
  type = "c",
  guide = TRUE,
  xscale = "continuous",
  yscale = "continuous",
  group = NULL,
  title = NULL,
  subtitle = NULL,
  caption = NULL,
  tag = NULL,
  plot_name = "xplot_rocplot",
  gg_theme,
  xp_theme,
  opt,
  quiet,
  thres_fixed = 0.5,
  like_col = NULL,
  obs_col = NULL,
  obs_target = NULL,
  auc_sprintf = "AUC: %.3f",
  ...
)

Arguments

xpdb: <xp_xtras> or <xpose_data> object
mapping: ggplot2 style mapping
type: See Details.
guide: Should the guide (e.g. unity line) be displayed.
xscale: Defaults to continuous.
yscale: Defaults to continuous.
group: Grouping for curves or points
title: Plot title
subtitle: Plot subtitle
caption: Plot caption
tag: Plot tag
plot_name: Metadata name of plot
gg_theme: As in xpose
xp_theme: As in xpose
opt: Processing options for fetched data
quiet: Silence extra debugging output
thres_fixed: Fixed threshold value for space
like_col: Column for likelihood/probability value
obs_col: Column for observed value
obs_target: Target observed value for likelihood
auc_sprintf: Format to apply to AUC label
...: Any additional aesthetics.

Value

The desired plot

Details

For type-based customization of plots:

c ROC curve (using geom_path)
k Key points on ROC curve (where on curve the threshold is thres_fixed) (using geom_point)
p ROC space points (using geom_point)
t ROC space text (using geom_text)
a AUC in bottom right (using geom_label)
