MAD: All pairs mean and sum of absolute differences

Description

All pairs mean and sum of absolute differences

Usage

MAD(x, ..., data, groups = NULL, ..fun.. = MAD_,
  na.rm = getOption("na.rm", FALSE))
SAD(x, ..., data, groups = NULL, ..fun.. = SAD_,
  na.rm = getOption("na.rm", FALSE))

Arguments

x

a numeric vector or a formula.

...

additional arguments passed through to MAD_ or SAD_. If x is a formala, ... should include an argument named data if the intent is to interpret the formala in a data frame.

data

a data frame in which to evaluate formulas (or bare names). Note that the default is data=parent.frame(). This makes it convenient to use this function interactively by treating the working envionment as if it were a data frame. But this ma

groups

a grouping variable, typically a name of a variable in data

..fun..

the underlying function used in the computation

na.rm

a logical indicating whether NAs should be removed before calculaing.

Value

• the mean or sum of the absolute differences between each pair of values in c(x,...).
