I have a DGElist object in edgeR, already processed with
calcNormFactors, estimateCommonDispersion and
estimateTagWiseDispersion. Now, I would like to identify tagwise
outliers in my data, I thought I could estimate NB distribution for
each tag. Given that a NB is defined by two parameters (r and p), I
assume that r = 1/x$tagwise.dispersion, how can I get tagwise p from
DGEList dataframe?
Thanks
