fct_collapse()
gains a group_other
argument to allow you to group all un-named levels into "Other"
. (#100, @AmeliaMN)
fct_cross()
creates a new factor containing the combined levels from two or more input factors, similar to base::interaction
(@tslumley, #136)
fct_inseq()
reorders labels in numeric order, if possible (#145, @kbodwin).
fct_lump_min()
preserves levels that appear at least min
times (can also be used with the w
weighted argument) (@robinsones, #142).
fct_match()
performs validated matching, providing a safer alternative to f %in% c("x", "y")
which silently returns FALSE
if "x"
or "y"
are not levels of f
(e.g. because of a typo) (#126, @jonocarroll).
fct_relevel()
can now level factors using a function that is passed the current levels (#117).
as_factor()
now has a numeric method. By default, orders factors in numeric order, unlike the other methods which default to order of appearance. (#145, @kbodwin)
fct_count()
gains a parameter to also compute the proportion (@zhiiiyang, #146).
fct_lump()
now does not change the label if no lumping occurs (@zhiiiyang, #130).
fct_relabel()
now accepts character input.
fct_reorder()
and fct_reorder2()
no longer require that the summary function return a numeric vector of length 1; instead it can return any orderable vector of length 1 (#147).
fct_reorder()
, fct_reorder2()
and as_factor()
now use the ellipsis package to warn if you pass in named components to ...
(#174).
fct_c()
now requires explicit splicing with !!!
if you have a list of factors that you want to combine. This is consistent with an emerging standards for handling ...
throughout the tidyverse.
fct_reorder()
and fct_reorder2()
have renamed fun
to .fun
to avoid spurious matching of named arguments.
All functions that take ...
use “tidy” dots: this means that you use can !!!
to splice in a list of values, and trailing empty arguments are automatically removed. Additionally, all other arguments gain a .
prefix in order to avoid unhelpful matching of named arguments (#110).
fct_lump()
gains w
argument (#70, @wilkox) to weight value frequencies before lumping them together (#68).
as_factor()
and fct_inorder()
accept NA levels (#98).
fct_explicit_na()
also replaces NAs encoded in levels.
fct_lump()
correctly acccounts for NA
values in input (#41)
lvls_revalue()
preserves NA levels.
Test coverage increased from 80% to 99%.
fct_drop()
now preserves attributes (#83).
fct_expand()
and lvls_expand()
now also take character vectors (#99).
fct_relabel()
now accepts objects coercible to functions by rlang::as_function
(#91, @alistaire47)
as_factor()
which works like as.factor()
but orders levels by appearance to avoid differences between locales (#39).
fct_other()
makes it easier to convert selected levels to “other” (#40)
fct_relabel()
allows programmatic relabeling of levels (#50, @krlmlr).
fct_c()
can take either a list of factors or individual factors (#42).
fct_drop()
gains only
argument to restrict which levels are dropped (#69) and no longer adds NA
level if not present (#52).
fct_recode()
is now checks that each new value is of length 1 (#56).
fct_relevel()
gains after
argument so you can also move levels to the end (or any other position you like) (#29).
lvls_reorder()
, fct_inorder()
, and fct_infreq()
gain an ordered
argument, allowing you to override the existing “ordered” status (#54).
