cv: A filter function for the coefficient of variation.

Description

cv returns a function with values for a and b bound. This function takes a single argument. It computes the coefficient of variation for the input vector and returns TRUE if the coefficient of variation is between a and b. Otherwise it returns FALSE

Usage

cv(a=1, b=Inf, na.rm=TRUE)

Arguments

a

The lower bound for the cv.

b

The upper bound for the cv.

na.rm

If set to TRUE any NA's will be removed.
