eval.blockdesign {AlgDesign}  R Documentation 
Evaluates a blocked design.
Description
A blocked design is evaluated.
Usage
eval.blockdesign(frml,design,blocksizes,rho=1,confounding=FALSE,center=FALSE)
Arguments
frml 
The formula used to create the blocked design. 
design 
The blocked design, which may be the design output by optBlock(). 
blocksizes 
A vector of blocksizes for the design. 
rho 
A vector, giving the ratios of whole to within variance components. 
confounding 
If confounding=TRUE, the confounding matrix will be output. 
center 
If TRUE, numeric variables will be centered before frml is applied. 
Value
confounding 
A matrix based on the design matrix in which the within block variables
have been centered about their block means. The columns of this matrix which give
the regression coefficients of each variable regressed on the others. If 
determinant.all.terms.within.terms.centered 

within.block.efficiencies 
The determinant criterion blocking efficiencies for the range of rho's input. A high efficiency indicates that there is little intrablock information to be recovered in the analysis. 
block.centered.properties 
A matrix with four rows. The columns correspond to constant, whole block terms and within block terms:
