(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.

(math/R-forcats) Updated 0.4.0 to 0.5.1

# forcats 0.5.1

* Re-license as MIT (#277).

* `fct_lump_n()` no longer uses a partial argument name (@malcolmbarrett, #276).

# forcats 0.5.0

* `as_factor()` gains a logical method that always returns a factor with
  levels "FALSE" and "TRUE" (#185).

* `fct_c()`, `fct_collapse()` and `fct_recode()` are now explicitly
  documented as using [dynamic dots](https://rlang.r-lib.org/reference/dyn-dots.html)
  (@labouz, #234).

* `fct_collapse()` now accepts a `other_level` argument, to allow a
   user-specified `Other` level (@gtm19, #194). It now correctly collapses
   factors when `other_level` is not `NULL` (#172), and makes `"Other"` the
   last level (#202) (@gtm19, #172 & #202)

* `fct_count()` no longer converts implicit NAs into explicit NAs (#151).

* `fct_inseq()` behaves more robustly when factor levels aren't all numbers
  (#221).

* `fct_lump()` has been split up into three new functions: `fct_lump_prop()`,
  `fct_lump_n()`, and `fct_lump_lowfreq()`. (@jonocarroll, #167, #142).
  All `fct_lump_()` functions check their inputs more carefully
  (@robinson_es, #169)

* `fct_reorder2()` gains a helper function `first2()`, that sorts `.y` by the
  first value of `.x` (@jtr13).

Log message:
Update all R packages to canonical form.

The canonical form [1] of an R package Makefile includes the
following:

- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
  needed), and CATEGORIES.

- HOMEPAGE is not present but defined in math/R/Makefile.extension to
  refer to the CRAN web page describing the package.  Other relevant
  web pages are often linked from there via the URL field.

This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.
