yield

yield, grams/plot

stems

nodes

podded nodes per stem

pods

pods per podded node

seeds

seeds per pod

weight

Examples

## Not run: 
  
  library(agridat)
  data(bond.diallel)
  dat <- bond.diallel
  
  # Because these data are means, we will not be able to reproduce
  # the anova table in Bond. More useful as a multivariate example.

  libs(corrgram)
  corrgram(dat[ , 3:11], main="bond.diallel",
           lower=panel.pts)

  # Multivariate example from sommer package
  corrgram(dat[,c("stems","pods","seeds")],
           lower=panel.pts, upper=panel.conf, main="bond.diallel")
  
  libs(sommer)           
  m1 <- mmer(cbind(stems,pods,seeds) ~ 1,
             random= ~ vs(female)+vs(male),
             rcov= ~ vs(units),
             dat)
