arrayWeightsQuick {limma} | R Documentation |
Estimates relative quality weights for each array in a multi-array experiment with replication.
arrayWeightsQuick(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 ExpressionSet . |
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.
This is a quick and dirty version of arrayWeights
.
Numeric vector of weights of length ncol(fit)
.
