Voter Formula

We use the voter formula, vote.formula, to indicate the number of actual voters (also known as the turnout), the number of eligible voters, and/or the number of seats each district elects to the main assembly. If this is omitted, the number of seats is assumed to be one per district and the turnout is assumed to be equal in all districts.

For example,

• vote.formula=cbind(turnout,eligible)~seats specifies all three quantities.

• vote.formula=cbind(turnout,eligible)~1 specifies turnout and eligible voters, and one seat per district.

• vote.formula=turnout~1 specifies turnout. The number of eligible voters is ignored, and seats are specified at one per district.

• vote.formula=~1 is the default option.
