esaps_object(path = NULL, dataset = NULL, name.file = NULL,
  extention = NULL, nCountry = NULL, name.year, name.country,
  name.M = NULL)

Arguments

path	Character vector containing one or more path names.
dataset	Electoral results by party. It can be a matrix, a data.frame or a list.
name.file	Name of the database file.
extention	Extension of the database format.
nCountry	Number of countries (number of sheets).
name.year	Name of the variable that contains years.
name.country	Name of the variable that contains the country.
name.M	Name of the variable that contains the district magnitude (M+1). It is for the calculation of endogenous and exogenous electoral volatility (Torcal and Lago, 2015).

Examples

votes <- list(data.frame(country = rep("ARG", 3),
                         year = c(1995, 2000, 2005),
                         party_A = c(40,10,20),
                         party_B = c(35,20,40),
                         party_C = c(25,70,40)),
              data.frame(country = rep("URY", 4),
                         year = c(1995, 2000, 2005, 2010),
                         party_A = c(30,30,20,20),
                         party_B = c(30,50,40, 30),
                         party_C = c(30,10,30, 25),
                         party_D = c(10,10,10,25)),
              data.frame(country = rep("BRA", 2),
                         year = c(1993, 1998),
                         party_A = c(30, 55),
                         party_B = c(70, 45)))

votes <- esaps_object(dataset=votes, name.country="country", name.year="year")
is(votes, "esaps")    ## TRUE
