## Electoral Data

### Description

This data set gives the results of the presidential election in France in 1988 for each department and all the candidates.

### Usage

    data(elec88)

### Format

`elec88` is a list with the following components:

tab

  a data frame with 94 rows (departments) and 9 variables (candidates)

res

  the global result of the election all-over the country

lab

  a data frame with two variables: `elec88$lab$dep` is a vector containing the names of the 94 french departments, `elec88$lab$reg` is a vector containing the names of the 21 French administrative regions.

area

  the data frame of 3 variables returning the boundary lines of each department. The first variable is a factor. The levels of this one are the row.names of `tab`. The second and third variables return the coordinates (x, y) of the points of the boundary line.

contour

  a data frame with 4 variables (x1, y1, x2, y2) for the contour display of France

xy

  a data frame with two variables (x, y) giving the position of the center for each department

neig

  the neighbouring graph between departments, object of the class `neig`

nb

  the neighbouring graph between departments, object of the class `nb`

Spatial

  the map of the french departments in Lambert II coordinates (an object of the class `SpatialPolygons` of `sp`)

Spatial.contour

  the contour of the map of France in Lambert II coordinates (an object of the class `SpatialPolygons` of `sp`)
