er_tte_add_censor: Add a censoring-marks layer

In erplots: Model-Agnostic Exposure-Response Plots

Add a censoring-marks layer

Description

Adds the censoring layer to a TTE plot, showing the times at which a subject was censored, read from the fit already stored internally within the plot object.

Usage

er_tte_add_censor(object, style = NULL, ...)

Arguments

object	Partially constructed plot (has S3 class er_tte).
style	Style used to draw the censoring marks layer. Can either be a string corresponding to one of the registered style labels (e.g., "ticks", the default), or a builder function used to compute the relevant plot object (see "Styles" below).
...	Additional named arguments forwarded to the style builder function when the plot is built.

Value

The input object, with the censor layer added.

Styles

The following pre-defined styles are available for this layer. Please see the documentation for the corresponding builder function to see what customisation options are available:

Label	Builder	Description
"ticks"	er_style_tte_censor_ticks()	Tick marks at each censoring time, on the curve's current step height (the only built-in, and the default).

See er_style_tte() for details on how style builder functions are defined for the TTE mini-grammar, should a custom style be required.
