estimateSizeFactors {DEXSeq} | R Documentation |
This function takes the count data from an ExonCountSet object (object), and estimates the size factors as follows: Each column (sample) is divided by the geometric means of the rows. The median of these ratios (skipping the genes with a geometric mean of zero) is used as the size factor for this column.
