Description

Computes a weighted mean of a numeric vector.

Usage

1
  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).
