MAD: All pairs mean and sum of absolute differences
Description
All pairs mean and sum of absolute differences
Usage
MAD(x, ..., data = NULL, groups = NULL, na.rm = getOption("na.rm", FALSE))
SAD(x, ..., data = NULL, groups = NULL, 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 m
groups
a grouping variable, typically a name of a variable in data
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,...).
