Description
weighted_mean() computes a weighted arithmetic mean. It enhances the
weighted.mean function with support for NA values in x. In
fact, weighted_mean() excludes element-pair with NA either from x or
w.
Usage
1
weighted_mean(x, w, exclude.Inf = TRUE)
Arguments
x
A numeric vector.
w
A numeric vector of weights the same length as x giving the
weights.
exclude.Inf
Logical.
Value
A numeric scalar.
Examples
1

x1 <- c(NA, 2, 3, 4, 5)
w1 <- c(5, NA, 3, 2, 1)
weighted_mean(x1, w1)
x2 <- x1[3:5]
w2 <- w1[3:5]
weighted_mean(x2, w2)
