stability.kilch {agrostab} | R Documentation |
This function calculates several stability parameters suggested by Kilchevsky & Khotyleva.
stability.kilch(dataf, res_var, gen_var, env_var, rep_var, plotIt = TRUE)
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 |
Returns a list of two objects:
the analysis of variance table
the data frame object of stability analysis results:
mean
mean value
OAC
common adaptive ability
sigma_ge
variance of GE interaction
sigma_CAC
variance of specific adaptive ability
S_g
relative stability
