weightedMean: Calculates weighted mean.

In andrie/surveyor: Tools for analysing, reporting and plotting survey data

Description

Computes a weighted mean of a numeric vector.

Usage

  weightedMean(x, w, na.rm = TRUE)

Arguments

x	a numeric vector containing the values whose weighted mean is to be computed.
w	a vector of weights the same length as x giving the weights to use for each element of x. Negative weights are treated as zero weights. Default value is equal weight to all values.#
na.rm	a logical value indicating whether NA values in x should be stripped before the computation proceeds, or not. If NA, no check at all for NAs is done. Default value is NA (for efficiency).
