wtd_sum R Documentation
Calculate a weighted sum
Description
This is an improvement on sum in base-r.
Usage
wtd_sum(x, w = NULL, error = F)
Arguments
x
(num vector) A vector of values.
w
(num vector) A vector of weights.
error
(lgl scalr) Whether to throw an error if there is no data at all or no pairwise complete cases. Default yes.
Details
It automatically handles missing data. It returns a useful error message if there are no complete cases.
Examples
set.seed(1)
X = rnorm(100)
set.seed(1)
W = runif(100)
wtd_sum(X) # not using weights
sum(X) #same as above
wtd_sum(X, W) #different
