| arrayWeights {limma} | R Documentation |
Estimates relative quality weights for each array a multi-array experiment with replication.
arrayWeights(y, fit)
y |
the data object used to estimate fit.
Can be of any class which can be coerced to matrix, including matrix, MAList, marrayNorm or exprSet. |
fit |
MArrayLM fitted model object |
Estimates the relative reliability of each array by measuring how well the expression values for that array follow the linear model.
Numeric vector of weights, so same length as ncol(fit).
