featureData missing after running RUVg

[symbiologist]

Hi Davide,

Lovely package!

When running RUV methods, the featureData of my SeqExpressionSet object disappears. For example:

fData(original_set) # returns my featureData table
ruvg_set <- RUVg(original_set, k = 1, cIdx = housekeeping)

Now when accessing fData(ruvg_set), it returns an empty data frame. However, pData works fine.

I can work around it by setting fData(ruvg_set) <- fData(original_set), but thought I should post it here for others.

Thank you!

David
