apportion

apportion provides different apportionment methods for allocating seats across states. These methods are also sometimes used for allocating seats by votes in proportional representation systems.

Installation

You can install the development version of apportion like so:

remotes::install_github('christopherkenny/apportion')

Example

apportion has several apportionment methods, each of which take two required arguments: - size: the number of seats to apportion across units - pop: a vector of population sizes for each unit

library(apportion)
## basic example code
data('state_2020')

app_adams(size = 435, pop = state_2020$pop)
#>  [1]  7  1  9  4 50  8  5  2 27 14  2  3 16  9  4  4  6  6  2  8  9 13  8  4  8
#> [26]  2  3  4  2 12  3 26 14  1 15  5  6 17  2  7  2  9 37  5  1 11 10  3  8  1

Implemented methods include:

• the Adams Method (app_adams())
• the Balinski Young Method (app_balinski_young())
• the Dean Method (app_dean())
• the D’Hondt Method (app_dhondt())
• the Hamilton-Vinton Method (app_hamilton_vinton())
• the Huntington-Hill Method (app_huntington_hill())
• the Jefferson Method (app_jefferson())
• the Webster Method (app_webster())
