calcul_: Calculating a class variable

In oceanis: Cartography for Statistical Analysis

Calculating a class variable

Description

Add to a data table a column whose values can be represented in a class analysis (ratio, part, evolution ...).

The calculation is based on volume data (from the population, for example).

Usage

calcul_ratio(data, var1, var2)

calcul_tx_evol_global(data, var1, var2)

calcul_tx_evol_ann_moy(data, var1, var2, nbAnnees)

calcul_part_ens(data, var)

calculette(data, formule = NULL)

Arguments

data	tableau de donnees (data.frame).
var1	chaine de caracteres (character). Variable en volume de la table.
var2	chaine de caracteres (character). Variable en volume de la table.
nbAnnees	nombre (numeric). Nombre d'annees appliquable au taux d'evolution annuel moyen.
var	chaine de caracteres (character). Variable en volume de la table.
formule	chaine de caracteres (character). Formule libre pour le calcul d'une variable de classes. Seuls les caracteres + - * / ^ ( ) sont acceptes.

Details

Les formules utilisees sont :

ratio

(data[,var1]/data[,var2])*100

tx_evol_global

((data[,var2]-data[,var1])/data[,var1])*100

tx_evol_ann_moy

((data[,var2]/data[,var1])^(1/nbAnnees)-1)*100

part_ens

(data[,var]/sum(data[,var],na.rm = TRUE))*100

Value

Retourne un objet data.frame.

Examples

data("donnees_monoloc")

ratio <- calcul_ratio(data = donnees_monoloc, var1 = "POP_2010", var2 = "POP_2015")
teg <- calcul_tx_evol_global(data = donnees_monoloc, var1 = "POP_2010", var2 = "POP_2015")
team <- calcul_tx_evol_ann_moy(data = donnees_monoloc, var1 = "POP_2010", var2 = "POP_2015",
nbAnnees = 5)
part <- calcul_part_ens(data = donnees_monoloc, var = "POP_2015")
