poorman 0.2.7

CRAN release: 2023-10-30

Eleventh CRAN release. This release:

• Adds a new function fill() that mimics tidyr::fill() (#113, @etiennebacher).
• Includes various performance improvements for grouped operations, pivot_wider() and pivot_longer() (@etiennebacher).
• Fixes CRAN issues.

poorman 0.2.6

CRAN release: 2022-08-17

Tenth CRAN release.

This update adds the following features:

• Initial versions of pivot_longer() and pivot_wider() have been added (#101, @etiennebacher).
• The .names argument in across() now accepts {.col} and {.fn} to automatically name new columns (#100, @etiennebacher).
• New function lst() to reproduce the outputs of tibble::lst(). It enables the creation of lists where elements are build sequentially (i.e depend on the previous ones) and are self-named (i.e the expression is used if no name is given) (#108).

The following fixes were also implemented:

• arrange() now works for descending character vectors (#99, @etiennebacher).
• arrange() now resets row names when they are numeric (#102, @etiennebacher).
• distinct() now resets row names when they are numeric (#106, @etiennebacher).

The CICD pipeline was also fixed such that users can now tests pull requests. The documentation is now built using HTML5.

poorman 0.2.5

CRAN release: 2021-03-28

Ninth CRAN release.

This update has added the following new features:

• summarise() can now revise grouping structures with the .groups argument (#57).
• group_by() can now drop groups formed by factor levels that don’t appear in the data with the .drop parameter (#63).
• New cumulative functions have been added: cumall(), cumany() and cummean() (#64).
• Additional tools for working with rownames have been added: has_rownames(), remove_rownames(), column_to_rownames(), rowid_to_column() (#66).
• filter() gains the .preserve parameters (#81).
• if_any() and if_all() were added (#80).

The following fixes were also implemented:

• mutate() now successfully evaluates functions defined in the scope of a parent function (#68).
• select_positions() now works if passed a combination of positive and negative values (#71).
• transmute() now keeps unnamed columns that it creates (#72).

The following refactorisations took place:

• When grouping data with group_by(), it will now create an object of class grouped_df and not grouped_data which keeps it consistent with the {dplyr} method name (#70). This should hopefully make transitioning packages from {dplyr} to {poorman} a little easier.

poorman 0.2.4

CRAN release: 2020-11-27

Eighth CRAN release.

This update has added the following new features:

• group_by() can now create new columns, grouping by the result (#58).
• with_groups() (#61).
• nth() (#62).
• mutate() can now relocate resulting mutations (#59).
• mutate() can now keep all, used, unused or none of the resulting mutations (#60).
• across() can now accept lambda style functions (#52).
• Columns created by summarise() are now immediately available (#20).
• cur_column() (#52).

The following fixes were also implemented:

• across() can now accept function names as characters (#56) - thanks @Eyayaw for pointing this out.
• An empty summarise() will now correctly return an empty data.frame (#55).

Other general refactorisations and improvements of note:

• group_by() is now an S3 generic.
• .default() methods are now .data.frame() methods.
• get_groups() has been removed in favour of group_vars().
• set_groups() has been replaced with groups_set() for API consistency.

poorman 0.2.3

CRAN release: 2020-11-12

Seventh CRAN release.

This update has added the following new features:

• across() (#37).
• na_matches and keep parameters have been added to mutate joins.
• list columns can now be mutated.
• Added the missing ability to use & in poor-select.

Fixes:

• Use of variables in relocate().

In addition there have been lots of improvements to documentation and many, many more tests added.

poorman 0.2.2

CRAN release: 2020-10-11

Sixth CRAN release.

This update has added the following new features:

• rename_with()
• group_cols() (#42)
• cur_data_all()
• nest_by() (#44)
• case_when() (#23)
• bind_cols() (#32)
• bind_rows() (#33)
• unite()

Performance upgrades and code improvements:

• pull() is now much faster thanks to @markfairbanks.
• %>% now allows you to pipe into a .; my thanks go to @moodymudskipper.

The following bugs have been squashed:

• Filter joins will no longer reduce to vectors thanks to @msberends.
• contains() no longer returns lists.
• relocate() can now use “tidy select” style column selections.

New documentation components have been added:

• An FAQ vignette has been added (#31).
• A pkgdown website has been added (#30).

poorman 0.2.1

CRAN release: 2020-07-01

Fifth CRAN release.

The update has added the following new features:

• distinct() (#17)
• slice_head(), slice_tail(), slice_min(), slice_max(), slice_sample() (#22)
• where() (#27)
• coalesce() (#28)
• group_split(), group_keys() (#29)
• na_if() (#34)
• recode() (#35)
• near() (#36)
• replace_na() (#38)

• glimpse() (#40)
• cur_data(), cur_group(), cur_group_id(), cur_group_rows() (#41)

There have also been a lot of refactoring for the internals of the package, particularly focusing on context awareness which allows for quite a few of these features (#40, #41) and grouped operations should now be more consistent. This update of course comes with a host of bug fixes including the renaming of multiple columns when using poorman’s version of tidyselect.

poorman 0.2.0

CRAN release: 2020-05-10

Fourth CRAN release.

This update has added the following new features:

• between() (#12)
• lead() and lag() (#13)
• n_distinct() (#16)
• window rank functions: cume_dist(), dense_rank(), min_rank(), ntile(), percent_rank(), row_number() (#18)

My thanks go to @msberends for their help on these features!

This update also refactors a lot of the code, hence the minor version bump. This includes:

• More support for “tidyselect” features such as !, :, -, c() and ()
• Removal of eval(parse(text = ...)
• Rework of grouped summaries

Finally, 0.2.0 includes many bug fixes:

• Joins now maintain their original order (#10)
• group_by() + mutate() now preserve row order (#14)
• Quote names are allowed in pull() (#15)

poorman 0.1.11

CRAN release: 2020-04-22

Third CRAN release.

This update adds the functions count(), tally(), add_count() and add_tally(). In order to achieve these, the functions n() and desc() have also been added. In addition, group_by() can now add additional groups to an already grouped data.frame.

poorman 0.1.10

CRAN release: 2020-04-13

Second CRAN release.

This update adds selection helper functions. See ?select_helpers for more information.

The following bugs have been fixed:

• mutate() column creations are immediately available, e.g. mtcars %>% mutate(mpg2 = mpg * 2, mpg4 = mpg2 * 2) will create columns named mpg2 and mpg4
• group_by() groups now persist in selections, e.g. mtcars %>% group_by(am) %>% select(mpg) will return am and mpg columns
• slice() now duplicates rows, e.g. mtcars %>% slice(2, 2, 2) will return row 2 three times
• summarize() is now exported
