Create confidence envelopes from a uhc_data_frame

Description

Simplifies sampled distributions in a uhc_data_frame to confidence envelopes

Usage

conf_envelope(x, levels = c(0.95, 1))

Arguments

x	⁠[uhc_data]⁠ An object of class uhc_data_frame, as returned by the function as.data.frame.uhc_data().
levels	⁠[numeric]⁠ A numeric vector specifying the desired confidence levels. Defaults to c(0.95, 1) to create 95% and 100% confidence intervals.

Details

This can dramatically improve plotting time for UHC plots by simplifying the many sampled lines down to the boundaries of a polygon.

Value

Returns a data.frame with columns:

• var: The name of the variable

• x: The x-coordinate of the density plot (the value of var).

• label: If var is a factor, the label for the value given by x.

• U: The y-coordinate of the density plot for the use distribution.

• A: The y-coordinate of the density plot for the availability distribution.

• ⁠CI*_lwr⁠: The lower bound of the confidence envelope for the corresponding confidence level.

• ⁠CI*_upr⁠: The upper bound of the confidence envelope for the corresponding confidence level.
