Extract effective (normalized) library sizes.
a object of class
other arguments are not currently used.
This function extracts normalized library sizes, equal to the original library sizes multiplied by the corresponding normalization factors, from an edgeR data object or fitted model object.
If the object contains a row-specific offsets (i.e., a non-sparse matrix of offsets), then the offsets for the first row are returned.
A numeric matrix of effective (normalized) library sizes.
log=TRUE, then natural log values are returned, equal to library size offsets for a NB log-linear model.
