Convert probe-weights or array-weights to a matrix of weights.
numeric matrix of weights, rows corresponding to probes and columns to arrays. Or vector of probe weights. Or vector of array weights.
numeric dimension vector of length 2, i.e., the number of probes and the number of arrays.
This function converts a vector or probe-weights or a vector of array-weights to a matrix of the correct size.
Probe-weights are repeated across rows while array-weights are repeated down the columns.
weights has length equal to the number of probes, it is assumed to contain probe-weights.
If it has length equal to the number of arrays, it is assumed to contain array-weights.
If the number of probes is equal to the number of arrays, then
weights is assumed to contain array-weights if it is a row-vector of the correct size, i.e., if it is a matrix with one row.
This function is used internally by the linear model fitting functions in limma.
Numeric matrix of dimension
An overview of functions in LIMMA used for fitting linear models is given in 06.LinearModels.
