Details

Data are the mean of 3 reps. These data were used to conduct a stability analysis of yield.

Examples

dat <- fan.stability

dat$env <- factor(paste(dat$loc, dat$year, sep=""))
require(reshape2)
dm <- acast(dat, gen~env, value.var="yield")
require(agricolae)
# Use 0.464 as pooled error from ANOVA.  Calculate yield mean/stability.
stability.par(dm, rep=3, MSerror=0.464) # Table 5 of Fan et al.
