Arguments

votes	numeric vector with number of votes for each party
n_seats	total number of seats
method	Apportionment method to use, as character. Not case sensitive. See details.
quorum	Vote threshold a party must reach. Used as quota of total votes within a district if less than 1 otherwise as number of votes.

Details

The following methods are available:

• d'hondt, jefferson, hagenbach-bischoff, floor: divisor_floor()

• sainte-lague, webster, round: divisor_round()

• adams, ceiling: divisor_ceiling()

• dean, harmonic: divisor_harmonic()

• huntington-hill, hill-huntington, geometric: divisor_geometric()

• hare-niemeyer, hamilton, vinton, largest_remainder_method: largest_remainder_method()

Note

Seats can also be apportioned among regions instead of parties. The parameter votes is then normally used with census data (e.g. population counts).

Examples

votes = c("Party A" = 651, "Party B" = 349, "Party C" = 50)

proporz(votes, 10, "sainte-lague")

proporz(votes, 10, "hill-huntington")

proporz(votes, 10, "hill-huntington", quorum = 0.05)

proporz(votes, 10, "jefferson", quorum = 70)
