Web5. For the base R matrix class we have the rowsum function, which is very fast for computing column sums across groups of rows. Is there an equivalent function or approach implemented in the Matrix-package? I'm particularly interested in a fast alternative to rowsum for large dgCMatrix-objects (i.e. millions of rows, but roughly 95% sparse). WebHere, we use data from 10.1126/sciadv.aba1983, downsampled for this demonstration and saved publicly on Zenodo:
