I am aware of the discussion in #53 , but I am still not sure if hardcoding it this way without checking the type of counts(object) is a good idea. For hdf5-backed object, the returned matrix can be of class "DelayedMatrix", which is not handled correctly by Matrix::rowSums(), just as an example.

Nice, thanks for the comment! That's why I didn't rush to merge it, the issue is quite big and requires some time to think and decide.

This is a temp fix. The correlation function
corandED2also need regular matrix as input, and converting the sparse matrix to regular isn't memory efficient.
