### Format

A data frame with 11 colums and 242 rows:

Variety

  A factor with 56 levels

Id

  A factor with 56 integral levels

pid

  A numeric variate containing plot numbers

raw

  Plot weights

Rep

  A factor with 4 levels

nloc

  Trial location (4)

yield

  Grain yield in t/ha

lat

  Spatial coordinate

long
