R Documentation

Coefficient of homeostaticity

Description

This function calculates the Khangildin's coefficient of homeostaticity

Usage

stability.hom(dataf, res_var, gen_var, env_var, rep_var, plotIt = TRUE)

Arguments

dataf	the name of the data frame containing the data to analyze.
res_var	the response variable.
gen_var	the genotypes variable.
env_var	the environments variable.
rep_var	the replications variable.
plotIt	a logical value specifying if plot should be drawn; default is TRUE

Value

Returns a data frame:

mean_all

the genotype's mean

mean_opt

the genotype's max yield value

mean_lim

the genotype's min yield value

sd

the genotype's standard deviation

hom
