Percent coefficient of variation (%CV)

This function computes the percent coefficient of variation of the values in x. If na.rm is TRUE then missing values are removed before computation proceeds.

Usage

cv(x, na.rm = FALSE)

Arguments

x

a numeric vector with untransformed data

na.rm

logical, if TRUE then NA values are stripped from x before computation takes place

Value

a numeric value. If x contains a zero or is not numeric, NA_real_ is returned

Examples

cv(c(5, 6, 3, 4, 5, NA), na.rm = TRUE)
