A function that takes in either a list of vectors or matrices
and computes a weighted average of them, where the weights are applied to
every element in the list.
Usage
weighted_combine_list(l, w, normalize_weights = TRUE)
Arguments
- l
a list that contains either vectors or matrices of the same dimension
that are to be combined
- w
a vector of weights, the weights should have the same number
of elements as `length(l)`
- normalize_weights
whether or not to force the weights to sum to 1,
default is true
Value
matrix or vector corresponding to the weighted average of
all of the elements in `l`
Examples
l <- list(c(1, 2, 3), c(4, 5, 6))
weighted_combine_list(l, w = c(0.5, 0.5)) ## returns c(2.5, 3.5, 4.5)
#> [1] 2.5 3.5 4.5
