(math/R-forcats) Updated 0.5.1 to 1.0.0
# forcats 1.0.0 ## New features * New `fct_na_value_to_level()` and `fct_na_level_to_value()` to convert NA values to NA levels and vice versa (#337). ## Minor improvement and bug fixes * All functions now validate their inputs, giving more useful errors if you accidentally misspecify an input. * `fct_collapse()` can now use `other_level = NA` (#291). * `fct_count()` works with factors that contain `NA`s in levels. * `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 (#138). * `fct_infreq()` gains the ability to weight by another variable using the `w` argument (#261). * `fct_inorder()` now works when not all levels appear in the data (#262). * `fct_lump_prop()` and friends now work correctly if you supply weights and have empty levels (#292). * `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 `fct_lump_*` functions (#274). * `fct_other()` no longer generates a warning if no levels are replaced with other (#265). * `fct_relevel()`, `fct_cross()`, and `fct_expand()` now error if you name the arguments in `...` since those names are ignored and your code probably doesn't do what you think it does (#319). * `fct_reorder()` and `fct_reorder2()` now remove `NA` values in `.x` with a warning (like `ggplot2::geom_point()` and friends). You can suppress the warning by setting `.na_rm = TRUE` (#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`) (#266). * `fct_unique()` now captures implicit missing values if present (#293). # forcats 0.5.2 * New `fct()` which works like `factor()` but errors if values of `x` are not included in the levels specification (#299) * `first2()` and `last2()` now ignore missing values in both `x` and `y` (#303). * Error messages are more informative.
