Block {DiGGer} | R Documentation |
Create a Block
object component of a DiGGer objective.
Block(rowsInBlock = 1, columnsInBlock = 1, blockVarianceRatio = 0.1)
rowsInBlock |
Number of rows in the template block for this
|
columnsInBlock |
Number of columns in the template block for this
|
blockVarianceRatio |
Variance component ratio for this block. A random block has a positive component otherwise the block is a fixed block. |
Blocks, fixed or random, are component objects in a DiGGer search
Objective
. Blocks tile down and across from Row 1 and Column 1
of a matrix representation of the design. The final block in a column
or row may be truncated to conform to the shape of the design. The
default Block()
will add a "nugget" variance component when
added to a DiGGer Objective
.
.nrpb |
Number of rows in the template block. |
.ncpb |
Number of columns in the template block. |
.gamma |
The variance component ratio associated with the blocking factor. |
