[ENH] Support forcats 1.0.0

[pwwang]

Feature Type

• [X] Adding new functionality to datar

• [X] Changing existing functionality in datar

• [ ] Removing existing functionality in datar

Problem Description

• https://github.com/tidyverse/forcats/releases/tag/v1.0.0

Feature Description

• New fct() which works like factor() but errors if values of x are not included in the levels specification

• first2() and last2() now ignore missing values in both x and y

• add fct_na_value_to_level()

• fct_explicit_na() is deprecated in favour of fct_na_value_to_level()

• fct_expand() gains an after argument so that you can choose where the new levels are placed

• fct_infreq() gains the ability to weight by another variable using the w argument

• fct_inorder() now works when not all levels appear in the data

• fct_lump_prop() and friends now work correctly if you supply weights and have empty levels

• fct_lump_n() and fct_lump_prop() will now create an "Other" level even if it only consists of a single level. This makes them consistent with the other fctlump* functions

• fct_other() no longer generates a warning if no levels are replaced with other

• fct_relevel(), fct_cross(), and fct_expand() now error if you name the arguments in **kwargs since those names are ignored and your code probably doesn't do what you think it does (see also https://github.com/tidyverse/forcats/issues/319).

• fct_reorder() and fct_reorder2() now remove NA values in _x with a warning. You can suppress the warning by setting _na_rm = True (see also https://github.com/tidyverse/forcats/issues/315).

• fct_reorder() and fct_reorder2() gain a new _default argument that controls the placement of empty levels (including levels that might become empty after removing missing values in _x) (see also https://github.com/tidyverse/forcats/issues/266).

• fct_unique() now captures implicit missing values if present
