0.2.1

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)
• group_data(), group_indices(), group_vars(), group_rows(), group_size(), n_groups(), groups() (#39)
• group_cols(), cur_data(), cur_group(), cur_group_id(), cur_group_rows(), cur_column() (#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}.

0.2.0

Fourth CRAN release.

This update has added the following new features:

• if_else() (#11)
• 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)

0.1.11

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.

0.1.10

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
