scvi-tools is an element of the scverse toolchest for single-cell omics data analysis.
The scviR package is a very elementary approach to interfacing between R, Bioconductor and scvi-tools. The long-term plan is to illustrate several aspects of variational inference (VI) applied to single cell genomics in a way that is convenient for Bioconductor users.
The package makes use of SingleCellExperiment and anndata representations of single-cell genomic assays.
Several points should be kept in mind when using this package:
As of May 2025, use BiocManager to install scviR in R 4.5.0 or above:
BiocManager::install("vjcitn/scviR")Be sure the remotes package has been installed. If you are working at a slow
internet connection, it may be useful to set options(timeout=3600) when running
functions
