## The function is currently defined as
function (x, weights = rep(1, length(x)), method = c("unbiased", 
    "ML")) 
{
    xMean <- weighted.mean(x, weights)
    xVar <- sum(weights * (x - xMean)^2)
    xVar <- switch(match.arg(method), unbiased = xVar/(sum(weights) - 
        1), ML = xVar/sum(weights))
    return(xVar)
  }
