Aggregate discrete values

Source: R/aggregate_weights.R
aggregate_weights.Rd

Aggregates discrete values together with their weights into a data frame or tibble.

Usage

aggregate_weights(y, weights, sum_to_one = FALSE)

Arguments

y

Vector of outcomes.

weights

Vector of weights, one for each of y. These need not sum to one, but must not be negative and non-NA.

sum_to_one

Logical; should the weights be normalized to sum to 1? Default is FALSE.

Value

Data frame with the following columns:

  • y: Increasing vector of unique values of y that have positive weight.

  • weight: Weights corresponding to each outcome.

Details

For a vector of outcomes y with a matching vector of weights, aggregate_weights() provides a single non-zero, non-NA weight per unique value of y.
