Batch Compare CDISC Datasets Across Submission Directories

Description

Scans two directories for matching dataset files, runs cdisc_compare() on each pair, and optionally generates a consolidated Excel report.

Usage

compare_submission(
  base_dir,
  compare_dir,
  format = NULL,
  id_vars = NULL,
  tolerance = 0,
  output_file = NULL
)

Arguments

base_dir	Path to directory containing base/reference files.
compare_dir	Path to directory containing comparison files.
format	File format to match: "xpt", "sas7bdat", "csv", or "rds". When NULL (default), auto-detected from the most common file type in base_dir.
id_vars	Optional character vector of ID variables (passed to each comparison). When NULL, CDISC-standard keys are auto-detected per domain.
tolerance	Numeric tolerance for floating-point comparisons (default 0).
output_file	Optional path to Excel (.xlsx) file for consolidated report.

Value

Named list of cdisc_compare() results, one per matched domain.

Examples

## Not run: 
  # Auto-detects format from directory contents
  results <- compare_submission("v1/", "v2/",
                                 output_file = "submission_diff.xlsx")

  # Explicit format
  results <- compare_submission("v1/", "v2/", format = "csv")

## End(Not run)
