cv {inTextSummaryTable}

Compute the percentage coefficient of variation, (in a scale from 0 to 100).

Description

The coefficient of variation is computed as: \frac{\sigma(x)}{\bar{x}}*100, with:

• \sigma(x): standard deviation of x

• \bar{x}: arithmetic mean of x

Usage

cv(x, na.rm = FALSE)

Arguments

x

Numeric vector.

na.rm

Logical, should NA value(s) be removed (FALSE by default)?

Value

Numeric vector of length 1 with coefficient of variation.
