rvec (version 1.0.0)

draws_sd: Standard Deviations, Variances, and Coefficients of Variation Across Random Draws

Description

Use standard deviations, variances, or coefficients of variation to summarise the distribution of random draws in an rvec.

Usage

draws_sd(x, na_rm = FALSE)
# S3 method for rvec_chr
draws_sd(x, na_rm = FALSE)
# S3 method for rvec
draws_sd(x, na_rm = FALSE)
draws_var(x, na_rm = FALSE)
# S3 method for rvec_chr
draws_var(x, na_rm = FALSE)
# S3 method for rvec
draws_var(x, na_rm = FALSE)
draws_cv(x, na_rm = FALSE)
# S3 method for rvec_chr
draws_cv(x, na_rm = FALSE)
# S3 method for rvec
draws_cv(x, na_rm = FALSE)

Value

A vector.

Arguments

x

An object of class rvec.

na_rm

Whether to remove NAs before calculating summaries. Default is FALSE.

Details

The coefficient of variation is the standard deviation divided by the mean.
