|A data frame with 5 columns and 670 rows:|
|yield||Grain yield in kg/ha|
|Column||A factor with 10 levels|
|Row||A factor with 67 levels|
|Variety||A factor with 532 levels|
The experiment consisted of 525 test lines which were randomly assigned to plots in a 67 row by 10 column array. There was a check plot variety every 6 plots within each column. That is, the check variety was sown on rows 1,7,13,. . . ,67 of each column. This variety was numbered 526. A further 6 replicated commercially available varieties (numbered 527 to 532) were also randomly assigned to plots with between 3 to 5 plots of each.
