coeff_var is a S3 generic that calculates the coefficient of
variation, defined as
$$CV(x) = \frac{sd(x)}{mean(x)}$$
coeff_var(x, na.rm = FALSE, ...)# S3 method for default
coeff_var(x, na.rm = FALSE, ...)
A numeric vector or matrix
Numeric vector, matrix, or array
Logical indicating whether NA values should be stripped
when calculating sums. Default: FALSE
Unused
If x is a matrix, it will calculate the CV for each column. If
x is a 3D array, it will calculate the coefficient of variation for
each row-column combination. If the input dimensions are \(n \times
n \times r\), a matrix with size \(n \times n\) will be returned.
