PackageCheck

Defines S4 classes for single-cell genomic data and associated
information, such as dimensionality reduction embeddings, nearest-neighbor
graphs, and spatially-resolved coordinates. Provides data access methods and
R-native hooks to ensure the Seurat object is familiar to other R users. See
