In burrm/lolcat: Miscellaneous Useful Functions

#' Calculate Subgroup Dispersion - Mean Absolute Deviation
#' 
#' Calculate subgroup dispersion using absolute deviation from subgroup average.
#'
#' @param fx Formula - defines formula for dependent variable and subgroups ( dv ~ v1 + v2 + ...)
#' @param data Data Frame - data frame with columns corresponding to variables in fx. 
#'
#' @return A vector containing absolute deviations from subgroup means.
