In Displayr/flipStatistics: Computes standard statistics (e.g., mean, standard deviation.)

#' StandardDeviation
#'
#' Computes the weighted variance of one or more variables
#'
#' @param x A \code{\link{data.frame}} or  \code{\link{matrix}}.
#' @param weights The sampling or replication weights.
#' @param method The way that the weights are addressed in the computation. Currently only "SPSS" is supported.

{
    sqrt(Variance(x, weights, method))
