Seat Distribution by D'Hondt

Calculates number of seats for the respective parties according to the method of d'Hondt.

dHondt(votes, parties, n_seats = 183)

Arguments

votes

Number of votes per party.

parties

Names of parties (must be same length as votes).

n_seats

Number of seats in parliament. Defaults to 183 (seats in Austrian parliament).

Value

A named integer vector of seat counts, one entry per party, in the same order as parties. The vector has a logical attribute ties: TRUE if two or more parties had equal claim to the last seat (i.e. the result is not uniquely determined and was resolved randomly), FALSE otherwise. When ties = TRUE, re-running with a different random seed may produce a different but equally valid seat distribution.
