public multi-modal single-cell data There is a scRNAseq Bioconductor package with a few different example scRNA-seq datasets. Are there any R packages that offer multiple modalities of single-cell data? For example, hashtags or ADTs or ATAC-seq. I am trying to find something that can be used for testing or for a quick tutorial. Preferably something that is on CRAN or Bioconductor.
These tutorials on Seurat multimodal data and the wrapper Seurat data are easy ways to start.

The wrapper has some cite-seq data preinstalled making it easy to work with benchmarked data sets

If you are using Seurat u can just as well have a look at Signac to start working with some sc-atac seq
