Test freqtable Updates

[mbcann01]

Overview

• 2026-02-11: I used Codex to work on the following issues en masse:
  • Work with contingency tables #34
  • Creating multiple one or n-way tables #36
  • Remove t_crit from default output #37
  • Create the freq_tbl function #39
  • Use group_by with freq_table #40
  • Decompose the freq_table function into multiple separate functions #45
• See Refactor frequency table workflow around grouped pipelines #47

Checks

• Test code from the wiki, and fix anything that isn't working. (in progress)
• Recreate vignettes.
• Update current testthat tests.
• Create new testthat tests.
• Improve the Roxygen documentation for freq_tbl()
• Create new vignettes using the built-in study data.
• Check freq_test()

Fix

• freq_tbl(): Change the column header from prop to percent when percent = TRUE.
• freq_tbl(): make the number of decimal places displayed consistent when percent = TRUE.
• freq_table(): One-way freq_table() code currently returns: Error in logit_ci(): ! logit_ci() could not find expected proportion/denominator columns.
• freq_table(): make the number of decimal places displayed for lcl and ucl consistent when percent = TRUE.
• freq_table(): Check to make sure the lcl and ucl are correct.
• Check the standalone ci functions.
• freq_tables(): Multiple one-way freq_tables() code currently returns: Error in logit_ci(): ! logit_ci() could not find expected proportion/denominator columns.
• freq_xtab(): This function wasn't created.

Next

• Submit to CRAN.
• Clean up the wiki.
• Can we use color to make the output easier to read?
• Should we create an option to output the results as a flextable?
• Replace the slowest parts of the freqtables code with C++ #48

Today’s changes, briefly:

1. Added percent-column renaming in both freq_tbl() and freq_table() when percent = TRUE:

   • prop* -> percent* (e.g., prop, prop_group, prop_total).

2. Added configurable decimal display (digits, default 2) for freq_tbl() and freq_table(), while keeping values numeric (not character).

3. Extended digits formatting in freq_table() to also apply to CI columns (lcl*, ucl*).

4. Fixed one-way freq_table() CI bug:

   • freq_table(outcome) now works without overall = TRUE by allowing CI helpers to handle one-way n + prop input (using sum(n) as denominator).

5. Expanded tests and docs/vignette notes to cover all of the above, and added pillar to package imports for numeric display formatting.
