Changes in version 0.4.1 (2026-01-09)                  

Internal changes

Patch to comply with

  - tidyverse/tidyr#1622
  - Matrix deprecating the use of as(., "dgeMatrix")

The documentation no longer uses the pipe (|>) operator, to avoid
dependency on R >= 4.1.0.

                 Changes in version 0.4.0 (2025-01-08)                  

Changes to apply_matrix(), apply_row() and apply_column()

Note that the changes also apply to the dfl/dfw variants.

Behavior changes

  - The functions are transitioning into taking only functions and
    formulas and no longer expressions. This change was made since the
    usage of formula and expression was almost identical, and the
    formula is clearer. The documentation has been updated to reflect
    this and the lifecyle as well.
    
    While this is currently still allowed, a warning will be issued that
    a formula should be used instead.

  - The function labels - what is used as column names when simplifying
    the results - no longer includes the "~" in the name when an
    expression was provided as a formula

  - The NULL matrices are no longer formatted during the simplification
    process. From now on, NULL is always returned for these matrices.
    
    For now, this is a soft deprecation and a lifecycle warning is
    issued.

Internal changes

Yet again, the functions have been refactored to improve both on clarity
and performance. The functions are now implemented using R6 classes. A
substantial performance has been noticed, between 2x to 20x faster,
depending on the apply flavor.

Improved functionality

It is now possible to expand matrixset objects following a join
operation even if the resulting tag names are no longer unique.

This is achieved by the introduction of the names_glue argument, which
when NULL (the default), the old behavior of preventing such join is
enforced - thus keeping back-compatibility.

Otherwise, the names_glue will provide instructions to the join
functions on how to make the resulting tag names unique.

Bug correction

  - Class adjustment now works for dual grouping.
  - Joining now works when the by argument is not named for every
    variable.

Internal change

New tests implemented for applying functions.

                 Changes in version 0.3.0 (2024-01-14)                  

Improved performance

A complete rewrite of the apply_ functions have been performed. The
initial goal was to have clearer codes to maintain, but from a user
perspective, an improvement on speed should be observed as well.

On another positive note, the opportunity of the rewrite was taken to
correct some bugs (see below).

Improved functionality

  - The mutate_matrix() function now has access to context functions.
    This implements #09.

  - The apply_ function family gained a new .force_name argument,
    available for the dfl/dfw versions. This allows better control in
    getting meaningful IDs to the outcomes.
    
    For instance, using .force_name solves the issue #12

  - Functions join_row_info() and join_column_info() now have more
    adjust possibilities to expand matrix sizes when the join operation
    results in matrix expansion. This implements #10.

Bug correction

  - The function mutate_matrix() can now accept statements such as
    mutate_matrix(ms, foo=bar), which was impossible before.
  - apply_matrix_df* now works when subgroup yields 1 x m or n x 1
    matrices. This solves #13
  - #12 has been resolved by the addition of the .force_name argument.
  - A miss-parametrization of function join_column_info() made it
    impossible to be executed. This has now been fixed.
  - matrixset objects with 0 rows can now be printed.
  - sub-setting matrixsets that yields 0-row objects is now possible.

                 Changes in version 0.2.0 (2023-07-08)                  

Main new Feature

All matrixset objects can now store matrices of class Matrix, which
allows sparse and other special matrices.

All matrixset extractors or other manipulation functions will work as
well.

This is a great way to annotate/manipulate special matrices.

Other New Features

  - There is now a check in apply_row_*/apply_column_* family functions
    to prevent names of function result to be identical to tags
    (typically, .rowname or .colname). (#1)
  - In the apply_* family functions, there is now a warning when
    specifying .input_list while .matrix_wise is FALSE. This answers #5

Bug Correction

  - It is now possible to replace row/col/dimnames of matrixset objects
    with partially or completely NULL dimnames. This fixes #2
  - When printing, the wrong columns were used for printing truncation.
    This is now fixed.
  - padding was sometimes off when printing, which is now resolved. This
    fixes #6

                 Changes in version 0.1.1 (2023-05-29)                  

  - Changed some examples that were commented out by wrapping them in
    tryCatch
  - Lines of the description field of the DESCRIPTION file no longer go
    over 80 characters. Also removed sets of consecutive space/linefeed.

                        Changes in version 0.1.0                        

CRAN submission.

                     Changes in version 0.0.0.9000                      

  - Added a NEWS.md file to track changes to the package.
