Calculate the median absolute deviation of the values from a contiguous subsection of specified vector.

Description

Compute the median absolute deviation for a specified vector of values. Only a contiguous subsection of the vector is used for the calculation, as the first and last position are set by user.

Usage

smad(pos, v)

Arguments

pos	a vector of 2 integer that represent the first and last positions of vector v to used for the calculation.
v	a vector of double containing the values used for the calculation. However, only a subsection of the vector, as set by pos, is used.

Value

a double which is the median of the values.

Examples

## A vector with the first and last positions to subset the value vector
position <- c(1, 8)

## A value vector used to do the calculation
values <- c(0.172073840, 0.219913919, 0.154459489, 0.040994620, -0.182843732,
    0.093052725, 0.170908930, 0.086624752, -0.003855011, -0.195791649)
