      - Creating Baseline Characteristics Tables
      - Data Cleaning and Preparation
      - Regression Analysis and Visualization
      - Model Evaluation and Comparison
      - Advanced Data Operations
  - Added merge_by_range() that merges data frames by keys and range
    matching. Can be used to merge data frames by time ranges, such as
    merging patient visits with exam results.
  - Improved return type consistency of first_mode().
  - Minor bug fixes and improvements.

                 Changes in version 1.3.0 (2026-03-07)                  

  - Added screen_data_list() that screens and joins multi-table clinical
    data by expression.
  - Added to_wide() that converts long-format clinical data in database
    to wide format for analysis and publication.
  - Added keep_by_keyword() to keep string segment by regex keyword
    position. Could be used to desensitize character vectors.
  - Minor bug fixes and improvements.

                 Changes in version 1.2.0 (2026-01-08)                  

  - Added data_overview() to get a quick overview of a data frame. It
    includes diagnostic information about common data issues and gives
    recommendations for data cleaning.
  - Added several outlier detection methods: mad_outlier(),
    zscore_outlier(), iqr_outlier().
  - Added merge_by_substring() to merge data frames by substring
    matching.
  - Added recursive argument to combine_files().

                 Changes in version 1.1.1 (2025-12-19)                  

  - Fixed PR plot visual inconsistency in classif_model_compare().
  - Added remove_inequal argument to value_initial_cleaning().
  - Changed the output of vec2code() to a more robust format.
  - Added a wrapper of vec2code(), where name2code(x) is equivalent to
    vec2code(names(x)).
  - Added time_roc_plot() that plot time-dependent ROC curve using
    timeROC::timeROC().
  - baseline_table() now uses invisible return if save_table is TRUE.
  - No longer showing the default row ids in auto-saved csv tables.
  - Minor bug fixes and improvements.

                 Changes in version 1.1.0 (2025-10-30)                  

  - Added time2 argument to functions that support cox models.
  - Added cluster argument to functions to utilize robust Robust
    Covariance Matrix Estimates in cox models and Generalized Estimating
    Equations in glm models.
  - Added PRAUC results and PR plot to classif_model_compare().
  - Refactored rcs_plot() and added a new predictor_effect_plot()
    function which can plot linear and categorical effects.
  - Added exclusion_count() which counts the number of excluded samples
    at each exclusion criteria.
  - Added na_min() and na_max(), similar to base::min() and base::max(),
    but return NA if all values are NA and omit NAs by default.
  - Fixed ggplot2 4.0.0 compatibility.
  - Minor improvements.

  - Added combine_multichoice() which combines multichoice results.
  - Added common_prefix() to find common prefixes in character vectors.
  - Added group argument to cut_by() to cut data by quantiles with
    groupings.
  - Added char_initial_cleaning() to clean character vectors.
  - Added indicate_duplicates() to determine duplicate elements,
    including their first occurrence.
