homogetest: homogetest

In ajpelu/auxiliar: Auxiliar R functions (miscellaneous)

Description

Check homogeneity of variances of different groups using several tests

Usage

homogetest(resp_var, factores, df)

Arguments

resp_var	is the name of the response variable
factores	a vector with the names of the variables used as factor
df	A dataframe object with a response variable and one or more independent variables

Details

The function computes the Levene's test for homogeneity of variance across groups (leveneTest) and Fligner-Killeen Test of Homogeneity of Variances (fligner.test for each of the variables included in factores vector.

Value

A data frame with several variables:

• fk_stat value of the Fligner-Killeen statistic

• fk_pvalue the p-value for the test

• lev_stat value of the Levene statistic

• lev_pvalue the p-value for the test

Examples

## Not run: 
factores <- c('disturb_year', 'site', 'interaction(disturb_year, site)')
homogetest(resp_var = 'rs', factores = factores, df = evires)

## End(Not run)
