CHANGES IN bit VERSION 4.0.0
NEW FEATURES
o new superclass ?booltype now allows proper method
dispatch even for two user defined booleans, e.g. (bit | bitwhich)
o new ordinal 'booltypes' nobool < logical < bit < bitwhich < \
which < ri
and diagnostic functions booltype() and is.booltype()
o bitwhich now has methods for [[ [ [[<- and [<-
o new functions 'c', '==', '!=', '|', '&', 'xor' for .booltype
o new function bitwhich_representation() to inspect the bitwhich
representation without the cost of unclass()
o new method 'is' for .which, .ri, .hi (and .booltype)
o new coercion generic as.booltype with .default method
o new coercion method as.logical.which
o new generic as.ri with methods for .ri and .default (lossy)
o new methods rep, rev, as.character and str for .bit and .bitwhich
o new methods all, any, min, max, range, sum, summary for .booltype, .which
o new method anyNA for all booltypes
o new dummy method 'is.na' for .bit, .bitwhich
o new function in.bitwhich much faster than %in%
o new integer sorting function bitsort() using bit_sort() or bit_sort_unique()
which can be by an order of magnitude faster than radix sorts
or falling back to one of countsort(), quicksort2(), quicksort3()
o new symmetric set function symdiff
o new functions copy(), reverse() for copying and reversing integer vectors
o new helper functions range_na(), range_nanozero(), range_sortna()
join multiple tasks in one go
o new fast unary functions for integers: bit_unique, bit_duplicated,
bit_anyDuplicated, bit_sumDuplicated
o new fast binary functions for integers: bit_in, bit_intersect, bit_union,
bit_setequal, bit_symdiff, bit_setdiff, bit_rangediff
o new fast unary functions for sorted integers: merge_rev,
merge_unique, merge_duplicated, merge_anyDuplicated, merge_sumDuplicated,
merge_first, merge_last,
o new fast binary functions for sorted integers:
merge_firstin, merge_firstnotin, merge_lastin, merge_lastnotin,
merge_match, merge_in, merge_notin,
merge_union, merge_intersect, merge_setdiff, merge_symdiff,
merge_setequal
o new even faster binary functions when the first argument is a range of \
integers:
merge_rangein, merge_rangenotin, merge_rangesect, merge_rangediff
o new function firstNA substantially faster than which.max(is.na(x))
o new function getsetattr() does setattr() but returns the old attr()
o new function get_length() directly returns LENGTH(SEXP)
circumventing all method dispatch for length()
o new methods rlepack.integer, rleunpack.rlepack anyDuplicated.rlepack
USER VISIBLE CHANGES
o license has been extendend from GPL-2 to GPL-2 | GPL-3
o S3methods are no longer exported in NAMESPACE
(except for .booltype)
o class bitwhich
- now is a fully functional alternative to bit vectors
- has argument order changed to (maxindex, x, poslength)
- its internal representation of bitwhich(0) has been changed
from FALSE to logical() and from unsorted to sorted integers
o class 'which' now carries an attribute 'maxindex' if available
o as.which() and bitwhich() now filter zeroes and store data unique(sort(x))
o as.which() now has methods for .which, .logical, .integer and .numeric
instead of .default.
o bit() and bitwhich() now behave more like logical(), without
arguments they return objects of length zero
o as.bit, as.bitwhich and as.which now have methods for class NULL
such that for example as.bit(c()) will return bit(0)
(wish of Martijn Schuemle)
o binary operators now allow for different lengths
and recycle instead of throwing an error
o xor.default now keeps the original definition of xor() and uses
a new method xor.logical to speed-up logicals
o the generics poslength and maxindex have been moved from package ff
with methods now for .default, .logical, .bit, .bitwhich, .which, .ri
o old method chunk.default has been renamed to chunks and now returns with names
(for backward compatibility chunk() with named arguments behaves as before)
o new method chunk.default calls chunks() along the length(x)
using typeof(x) or vmode(x), this replaces chunk.bit from package ff
o clone.default now uses R's C-function duplicate()
and clone.list has been removed
o intisasc() and intisdesc() have a new argument
na.method=c("none","break","skip") to \
specify tie handling
TESTING and DOCUMENTATION
o there are much more regression tests now
o testing uses package testthat
o documentation uses package roxygen2 now
o new vignettes bit-demo, bit-usage and bit-performance
BUG FIXES
o assignment functions '[<-.bit' now behave like '[<-.logical' when it
comes to NAs or ZEROs in subscripts
o length<-.bit no longer tries to access memory before it is allocated
o as.bit.bitwhich now handles non-positive bitwhich correctly
o declare as static many functions/variables in bit.c. (Thanks to Brian Ripley)
