sd {rvec}

Standard Deviation, Including Rvecs

Description

Calculate standard deviation of x, where x can be an rvec. If x is an rvec, separate standard deviations are calculated for each draw.

Usage

sd(x, na.rm = FALSE)

Arguments

x

A numeric vector or R object, including an rvec().

na.rm

Whether to remove NAs before calculating standard deviations.

Details

To enable different behavior for rvecs and for ordinary vectors, the base R function stats::sd() is turned into a generic, with stats::sd() as the default.

For details on the calculations, see the documentation for stats::sd().

Value

An rvec, if x is an rvec. Otherwise typically a numeric vector.
