List Cached Datasets — on_cache

Returns a tibble of all datasets currently in the openneuroR cache.

Usage

on_cache_list()

Value

A tibble with columns:

dataset_id: Dataset identifier (e.g., "ds000001")
snapshot_tag: Cached snapshot version (may be NA if unknown)
n_files: Number of cached files
total_size: Total size in bytes
size_formatted: Human-readable size (e.g., "1.2 GB")
cached_at: When first cached (ISO 8601 timestamp)
type: Type of cached data: "raw" for raw dataset files, "derivative" for fMRIPrep/MRIQC outputs, or "raw+derivative" if both are cached

Examples

if (FALSE) { # \dontrun{
# List all cached datasets
on_cache_list()

# Check total cache usage
cached <- on_cache_list()
sum(cached$total_size)  # total bytes

# Filter to only derivatives
cached[grepl("derivative", cached$type), ]
} # }
