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
# 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> #>  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>.
