        skewness(x, na.rm=FALSE)

   AArrgguummeennttss::

          x: a numeric vector containing the values whose skew-
             ness is to be computed.

      na.rm: a logical value indicating whether NA values
             should be stripped before the computation pro-
             ceeds.

   DDeessccrriippttiioonn::

        Computes the skewness of the values of `x'.

        If N = length(x), then the skewness of x is defined as

               N^(-1) sd(x)^(-3) sum_i (x_i - mean(x))^3

   VVaalluuee::

        Returns the skewness of x.

        x<-rnorm(100)
        skewness(x)
