The family of “set” functions has been renamed to include a
set_ prefix, for example, iv_union() is now
iv_set_union(). This has been done to align with the new
family of vctrs set functions, like vec_set_union(), and to
reduce the ambiguity between the new iv_diff() helper and
iv_difference() (now iv_set_difference()). The
old names are deprecated, and will be removed in a future release
(#35).
iv_complement() ->
iv_set_complement()iv_union() -> iv_set_union()iv_intersect() ->
iv_set_intersect()iv_difference() ->
iv_set_difference()iv_symmetric_difference() ->
iv_set_symmetric_difference()iv_pairwise_*()
functions that share the same suffixes.New family of functions that perform the inverse of
iv_between(), i.e. rather than detecting if
needles[i], a vector value, falls between any
intervals in haystack, an iv, these detect if
needles[i], an interval, includes any value from
haystack, a vector. These functions are:
iv_includes(), iv_locate_includes(),
iv_count_includes(), and
iv_pairwise_includes() (#41).
New family of functions for identifying interval
containers, which are intervals that aren’t contained within
any other interval. These functions are: iv_containers(),
iv_identify_containers(),
iv_identify_container(), and
iv_locate_containers() (#20).
New iv_diff() for generating an iv from an existing
vector that is in strictly increasing order (#17).
New iv_span() for computing a summary interval that
encompasses the entire range of an existing iv (#49).
New Examples vignette that links out to Stack Overflow questions
that were solved with ivs. View it locally with
vignette("examples", package = "ivs").
vec_ptype() and vec_ptype_finalise()
methods have been added for the iv class. This should result in slightly
better performance when combining many ivs together (#27).
iv_locate_overlaps(),
iv_locate_precedes(), iv_locate_follows(),
iv_locate_between(), and iv_locate_includes()
have all gained the relationship argument from the
underlying engine, vctrs::vec_locate_matches()
(#45).
iv_proxy() now returns the input unchanged if it
doesn’t implement an S3 method, rather than erroring. In combination
with is_iv(), this provides a way to check if an input
implements a proxy method and to implement different behaviors depending
on the result.
In iv(), incomplete value propagation is now done
before the start < end check, which fixes an
inconsistent edge case (#36).
You can now combine an iv containing unspecified components with any other iv (#33).
The "iv" class name has been renamed to the more
specific "ivs_iv" to better insulate it from potential
collisions with classes from other packages (#25).
Improved on the call reported by errors thrown in ivs (#23).
Switched to using vec_run_sizes() and
vec_chop(sizes =) internally, which improves performance in
some cases (#50).
Added a NEWS.md file to track changes to the
package.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
