R: Coerce a 'uhc_data' object to 'data.frame'

as.data.frame.uhc_data {amt}

R Documentation

Coerce a `uhc_data` object to `data.frame`

Description

Coerces uhc_data from list to data.frame

Usage

## S3 method for class 'uhc_data'
as.data.frame(x, row.names = NULL, optional = FALSE, ...)

Arguments

`x`	`⁠[uhc_data]⁠` An object of class `uhc_data`, as returned by the function `prep_uhc()`.
`row.names`	Included for consistency with generic `as.data.frame()`. Currently ignored.
`optional`	Included for consistency with generic `as.data.frame()`. Currently ignored.
`...`	Included for consistency with generic `as.data.frame()`. Currently ignored.

Details

This coercion aims to keep all of the information contained in the uhc_data list in the resulting data.frame representation. Factors are converted to numeric, but the levels are retained in the column "label".

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).
y: The y-coordinate of the density plot (the probability density for a numeric var and the proportion for a factor var).
dist: The distribution represented. Either "U" for used, "A" for available, or "S" for sampled.
iter: The iteration number if dist == "S".
label: The label if var is a factor.
