Package: fmridataset 0.8.9

Bradley Buchsbaum

fmridataset: Unified Container for fMRI Datasets

Provides a unified S3 class 'fmri_dataset' for representing functional magnetic resonance imaging (fMRI) data from various sources including raw NIfTI files, BIDS projects, pre-loaded NeuroVec objects, and in-memory matrices. Features lazy loading, flexible data access patterns, and integration with neuroimaging analysis workflows.
