CHANGES IN bit VERSION 1.1-14
BUG FIXES
o bit[i] and bit[i]<-v now check for non-positive integers
which prevents a segfault when bit[NA] or bit[NA]<-v
CHANGES IN bit VERSION 1.1-13
USER VISIBLE CHANGES
o logical NA is now mapped to bit FALSE as in ff booleans
o extractor function '[.bit' with positive numeric subscripts
(integer, double, bitwhich) now behaves like '[.logical' and returns
NA for out-of-bound requests and no element for 0
o extractor function '[[.bit' with positive numeric (integer, double,
bitwhich) subscripts now behaves like '[[.logical' and throws an error
for out-of-bound requests
o extractor function '[.bit' with range index subscripts (ri)
subscripts now behaves like '[[.bit' and throws an error
for out-of-bound requests
o assignment functions '[<-.bit' and '[[<-.bit' with positive numeric
(integer, double, bitwhich) subscripts now behave like '[<-.logical' and
'[[<-.logical' and silently increase vector length if necessary
o assignment function '[<-.bit' with range index subscripts (ri) now
behaves like '[[<-.bit' and silently increases vector length if necessary
o rlepack() is now a generic with a method for class 'integer'
o rleunpack() is now a generic with a method for class 'rlepack'
o unique.rlepack() now gives correct results for unordered sequences
o anyDuplicated.rlepack() now returns the position of the first
duplicate and gives correct results for unordered sequences
TUNING
o The package can now compiled with 64bit words instead of 32bit words,
since we only measured a minor speedup, we left 32bit as the default.
BUG FIXES
o extractor and assignment functions now check for legal (positive)
subscript bounds, hence illegally large subscripts or zero no longer
cause memory violations
