frequency_weights() creates a vector of frequency weights which allow you to compactly repeat an observation a set number of times. Frequency weights are supplied as a non-negative integer vector, where only whole numbers are allowed.

Usage

frequency_weights(x)

Arguments

x

An integer vector.

Value

A new frequency weights vector.

importance_weights()

Examples

# Record that the first observation has 10 replicates, the second has 12
# replicates, and so on
frequency_weights(c(10, 12, 2, 1))
#> <frequency_weights[4]>
#> [1] 10 12  2  1

# Fractional values are not allowed
try(frequency_weights(c(1.5, 2.3, 10)))
#> Error in frequency_weights(c(1.5, 2.3, 10)) :
#>   Can't convert x <double> to <integer>.
