Hey @jpark27, It seems to complain about `packageVersion()` not being available. Does it happen in RStudio? Is this function available in vanilla R? I cannot reproduce this when using R...

Hey @wlason, What is the amount of features you're using there as input? One way to make it work has been using only a subset of highly variable features. You...

Thanks, @ilia-kats! I especially appreciate the code reduction — it's a great direction, and maybe we can eliminate even more code in the `.update()` functionality to make it simpler in...

I think it could largely depends on the dataset. In MEFISTO, a subset of samples adjusted by the `frac_inducing` is used for this. In some datasets, if samples / cells...

Thanks, @MUCDK! Which other arguments from `anndata.read` would you like to see here? Is it about propagating arguments like `as_sparse`, `as_sparse_fmt`, and `chunk_size` to the readers of individual modalities?

I don't think we should make MuData depend on scanpy though. If we reuse `scanpy.readwrite._check_datafile_present_and_download`, would it make sense to have it in `muon.read()` instead?

Hey @mruffalo, Thanks for an interesting use case! Happy to discuss what we can do here to support it. Can you help me understand what an "empty" MuData object would...

Hey @mruffalo, It should be possible to instantiate an empty MuData now: ```py from mudata import AnnData, MuData MuData() # MuData object with n_obs × n_vars = 0 × 0...

Do you have any steps to reproduce that, @raozuming?

We improved a few things about `.update()` since v0.2.3. Closing it due to inactivity, please reopen if there's still an issue!
