Error when fiiting AR residual structure with ASReml-R

Hello,

I'm trying to fit the following "classroom" MET model with a test
dataset, but I get an error coming from the rcov.

met.1.asr <- asreml(yld ~ Site, random =~ diag(Site):geno,
rcov=~at(Site):ar1(Column):ar1(Row), data=mmData)

Error in asreml.rdflt2(Y, Var[!which], section, lvl,
dataFrame[which.row, :

  Error model specifies 792 observations, but data section has 2202 rows

The data structure is fairly unbalanced and I have sorted the dataframe
by Site, Column and Row (all defined as factors) as required by the
package.

         1 2 4 5 6 7 8 9 10 11 12 13 14 15

  Site1 0 0 0 72 72 0 0 72 72 72 72 0 0 0

  Site2 0 0 0 70 72 66 72 72 72 72 67 72 72 72

  Site3 71 72 72 72 72 0 0 66 72 0 0 0 0 0

  Site4 0 0 0 72 72 0 0 72 65 0 0 71 70 72

I wonder if Columns and Rows need to be renumbered in some way or I am
specifying the error model incorrectly.

As a general rule, do Columns and Rows need to be (re)numbered
consecutively? I would not think so but ...

Thanks for your assistance.

Fernando
