    verbose = TRUE, main = "Array Weights", ...)

Arguments

aw	a named, numeric vector of array weights [optional]
data	if aw=NULL, then you can specify an object that must be compatible with arrayWeights. see arrayWeights
design	if aw=NULL, you can specify the design matrix for calculating the array weights. defaults to the unit vector.
