export_interactive_roc: Generate svg code for an ROC curve object

Description

Takes a ggplot object that contains a GeomRoc layer and returns a string that contains html suitable for creating a standalone interactive ROC curve plot.

Usage

export_interactive_roc(
  ggroc_p,
  add.cis = TRUE,
  hide.points = FALSE,
  prefix = "a",
  width = 6,
  height = 6,
  omit.js = FALSE,
  style = style_roc(theme = theme_grey()),
  ...
)

Value

A character object containing the html necessary to plot the ROC curve in a web browser

Arguments

ggroc_p: A ggplot object with a GeomRoc layer and optionally a GeomRocci layer as returned by geom_roc and/or geom_rocci. It can be modified with annotations, themes, etc.
add.cis: Logical, if true, removes the current confidence interval layer (if present) and replaces it with a denser layer of confidence regions
hide.points: Logical, if true, hides points layer so that points with cutoff values are only visible when hovering. Recommended for plots containing more than 3 curves.
prefix: A string to assign to the objects within the svg. Enables unique identification by the javascript code
width, height: Width and height in inches of plot
omit.js: Logical. If true, omit inclusion of javascript source in output. Useful for documents with multiple interactive plots
style: A call to the function style_roc
...: Other arguments passed to geom_rocci when add.cis = TRUE

Details

If you intend to include more than one of these objects in a single page, use a different prefix string for each one. To use this function in knitr, use the chunk options fig.keep='none' and results = 'asis', then cat() the resulting string to the output. See the vignette for examples. Older browsers (< IE7) are not supported.
