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")
#> Party A Party B Party C
#> 7 3 0
proporz(votes, 10, "hill-huntington")
#> Party A Party B Party C
#> 6 3 1
proporz(votes, 10, "hill-huntington", quorum = 0.05)
#> Party A Party B Party C
#> 6 4 0
proporz(votes, 10, "jefferson", quorum = 70)
