chop_quantiles() and brk_quantiles() gain a new weights argument,
letting you chop by weighted quantiles using Hmisc::wtd.quantile().brk_quantiles() may now return singleton breaks, producing more
accurate results when x has duplicate elements.raw argument to
lbl_* functions now always gives a deprecation warning.fmt in lbl_* functions will be taken as arguments to
base::format. This gives more flexibility in formatting, e.g., units
breaks.chop_n() gains a tail argument, to deal with a last interval containing
less than n elements. Set tail = "merge" to merge it with
the previous interval. This guarantees that all intervals contain at least
n elements.chop_equally() may return fewer than groups groups when there are
duplicate elements. We now warn when this happens.chop_n() could return intervals with fewer than n elements
when there were duplicate elements. The new algorithm avoids this, but
may be slower in this case.endpoint_labels() methods gain an unused ... argument to satisfy R CMD CHECK.There are important changes to close_end.
close_end is now TRUE by default in chop() and fillet().
In previous versions:
chop(1:2, 1:2)
## [1] [1, 2) {2}
## Levels: [1, 2) {2}
Whereas now:
chop(1:2, 1:2)
## [1] [1, 2] [1, 2]
## Levels: [1, 2]
close_end is now always applied after extend. For example, in previous
versions:
chop(1:4, 2:3, close_end = TRUE)
## [1] [1, 2) [2, 3] [2, 3] (3, 4]
## Levels: [1, 2) [2, 3] (3, 4]
Whereas now:
chop(1:4, 2:3, close_end = TRUE)
## [1] [1, 2) [2, 3) [3, 4] [3, 4]
## Levels: [1, 2) [2, 3) [3, 4]
We changed this behaviour to be more in line with user expectations.
If breaks has names, they will be used as labels:
chop(1:5, c(Low = 1, Mid = 2, High = 4))
## [1] Low Mid Mid High High
## Levels: Low Mid High
Names can also be used for labels in probs in chop_quantiles() and
proportions in chop_proportions().
There is a new raw parameter to chop(). This replaces the parameter
raw in lbl_* functions, which is now soft-deprecated.
lbl_manual() is deprecated. Just use a vector argument to labels instead.
A labels argument to chop_quantiles() now needs to be explicitly named.
I expect these to be the last important breaking changes before we release version 1.0 and mark the package as "stable". If they cause problems for you, please file an issue.
chop_fn(), brk_fn() and tab_fn() chop using an arbitrary function.lbl_endpoint() has been renamed to lbl_endpoints(). The old version will
trigger a deprecation warning. lbl_endpoints() gains first, last and
single arguments like other labelling functions.chop_pretty(), brk_pretty() and tab_pretty() functions use
base::pretty() to calculate attractive breakpoints. Thanks @davidhodge931.chop_proportions(), brk_proportions() and tab_proportions()
functions chop x into proportions of its range.chop_equally() now uses lbl_intervals(raw = TRUE) by default, bringing it
into line with chop_evenly(), chop_width() and chop_n().lbl_midpoints() function labels breaks by their midpoints.lbl_discrete() gains a single argument.ts, xts::xts and zoo::zoo objects.chop() is more forgiving when mixing different types, e.g.:
Date objects with POSIXct breaks, and vice versabit64::integer64 and doubleslbl_discrete() sometimes had ugly label formatting.first and last arguments are now passed to
glue::glue(). Variables l and r represent the left and right endpoints
of the intervals.chop_mean_sd() now takes a vector sds of standard deviations, rather than
a single maximum number sd of standard deviations. Write e.g.
chop_mean_sd(sds = 1:3) rather than chop_mean_sd(sd = 3). The sd argument
is deprecated.groups argument to chop_evenly(), deprecated in 0.4.0, has
been removed.brk_left() and brk_right(), deprecated in 0.4.0, have been removed.knife(), deprecated in 0.4.0, has been removed.lbl_format(), questioning since 0.4.0, has been removed.lbl_dash() and lbl_intervals() have been reordered for
consistency with other labelling functions.units from the units package,
difftime objects, package_version objects, etc.
{glue} package has become a hard dependency. It is used in many places to
format labels.lbl_glue() function using the {glue} package. Thanks to @dpprdan.labels = NULL to return integer codes.first, last and single can be used in lbl_intervals()
and lbl_dash(), to override the first and last interval labels, or to
label singleton intervals.lbl_dash() and lbl_discrete() use unicode em-dash where possible.brk_default() throws an error if breaks are not sorted.tab() and friends no longer display an x as the variable name.lbl_endpoint() was erroring for some types of breaks.New arguments first and last in lbl_dash() and lbl_discrete() allow you
to override the first and last interval labels.
Fixes for CRAN.
chop_width().
left = FALSE by default.chop(1:4, 1) was erroring.The new version has some interface changes. These are based on user experience,
and are designed to make using chop() more intuitive and predictable.
chop() has two new arguments, left and close_end.
left = FALSE is simpler and more intuitive than wrapping
breaks in brk_right().brk_left() and brk_right() have been kept for now, but cannot be used to
wrap other break functions.close_end is simpler than passing close_end into
brk_left() or brk_right() (which no longer accept this argument directly).left = TRUE by default, except for non-numeric objects in
chop_quantiles() and chop_equally(), where left = FALSE works better.close_end is now FALSE by default.
chop(3, 1:3) puts 3 into a
different category than chop(3, 1:4).close_end is TRUE by default for chop_quantiles(), chop_n() and
similar functions. This ensures that e.g.
chop_quantiles(x, c(0, 1/3, 2/3, 1)) does what you would expect.The groups argument to chop_evenly() has been renamed from groups to
intervals. This should make it easier to remember the difference between
chop_evenly() and chop_equally(). (Chop evenly into n equal-width
intervals, or chop equally into n equal-sized groups.)
knife() has been deprecated to keep the interface slim and
focused. Use purrr::partial() instead.
Date and datetime (POSIXct) objects can now be chopped.
chop_width() accepts difftime, lubridate::period or lubridate::duration
objectschop_ functions work as well.Many labelling functions have a new fmt argument. This can be a string
interpreted by sprintf() or format(), or a 1-argument formatting function
for break endpoints, e.g. scales::label_percent().
Experimental: lbl_discrete() for discrete data such as integers or (most)
dates.
There is a new lbl_endpoint() function for labelling intervals solely by
their left or right endpoint.
brk_mean_sd() now accepts non-integer positive numbers.
Add brk_equally() for symmetry with chop_equally().
Minor tweaks to chop_deciles().
Bugfix: lbl_format() wasn't accepting numeric formats, even when
raw = TRUE. Thanks to Sharla Gelfand.
First CRAN release.
Changed kut() to kiru(). kiru() is an alternative spelling for chop(),
for use when the tidyr package is loaded.
lbl_sequence() has become lbl_manual().
lbl_letters() and friends have been replaced by lbl_seq():
lbl_letters() use lbl_seq()lbl_LETTERS() use lbl_seq("A")lbl_roman() use lbl_seq("i")lbl_ROMAN() use lbl_seq("I")lbl_numerals() use lbl_seq("1")lbl_seq("A:"), lbl_seq("(i)")Added a NEWS.md file to track changes to the package.
Default labels when extend = NULL have changed, from
[-Inf, ... and ..., Inf] to [min(x), ... and ..., max(x)].
