Usage

Data sources are discovered by scanning the package directory structure. List available datasets with list_data_sources().

Access data using the connection function:

# Connect to any data source (e.g., CDISC Pilot data)
db <- connect_clinical_data("cdisc_pilot")

# List available datasets
db$adam$list_content_cnt()

# Read a dataset
adsl <- db$adam$read_cnt("adsl")

# See all available data sources
list_data_sources()

Data Format

Datasets are stored in Parquet format:

• Columnar storage

• Fast reads

• Compression

• Cross-platform compatibility
