conf_envelope: 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))

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.

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.
