draws_median: Medians, Means, and Modes Across Random Draws

In rvec: Vectors Representing Random Variables

Medians, Means, and Modes Across Random Draws

Description

Summarise the distribution of random draws in an rvec, using means, medians, or modes.

Usage

draws_median(x, na_rm = FALSE)

## S3 method for class 'rvec_chr'
draws_median(x, na_rm = FALSE)

## S3 method for class 'rvec'
draws_median(x, na_rm = FALSE)

draws_mean(x, na_rm = FALSE)

## S3 method for class 'rvec'
draws_mean(x, na_rm = FALSE)

## S3 method for class 'rvec_chr'
draws_mean(x, na_rm = FALSE)

draws_mode(x, na_rm = FALSE)

## S3 method for class 'rvec'
draws_mode(x, na_rm = FALSE)

Arguments

x	An object of class rvec.
na_rm	Whether to remove NAs before calculating summaries. Default is FALSE.

Details

When method is "mode", reduce_rvec() returns the most common value for each observation. When there is a tie, it returns NA.

Value

A vector.
