Arguments

celSetList

an object of class AffymetrixCelSetList

units

the units to be extracted. Can be either a numeric vector or a character string with the unitNames as on the appropriate cdf. If not supplied, all units will be returned.

which

specify which elements of the celSetList should have data extracted from them. If not supplied, data from all elements of the celSetList will be returned

firstOnly

if firstOnly=TRUE, only the first cell from each unit will be extracted. If firstOnly=FALSE all cells from each unit will be extracted.

log

should the data be log-transformed

Details

During the BMEA process, contrast, model parameters & background priors are all saved as AffymetrixCel Files. This enables simple extraction of saved data for any combination of units & files.

Value

Returns either a matrix or array, depending on which data is requested
