%description
|
|
True boolean datatype (no NAs), coercion from and to logicals, integers and
|
|
integer subscripts; fast boolean operators and fast summary statistics. With
|
|
'bit' vectors you can store true binary booleans {FALSE,TRUE} at the expense of
|
|
1 bit only, on a 32 bit architecture this means factor 32 less RAM and ~ factor
|
|
32 more speed on boolean operations. Due to overhead of R calls, actual speed
|
|
gain depends on the size of the vector: expect gains for vectors of size >
|
|
10000 elements. Even for one-time boolean operations it can pay-off to convert
|
|
to bit, the pay-off is obvious, when such components are used more than once.
|
|
Reading from and writing to bit is approximately as fast as accessing standard
|
|
logicals - mostly due to R's time for memory allocation. The package allows to
|
|
work with pre-allocated memory for return values by calling .Call() directly:
|
|
when evaluating the speed of C-access with pre-allocated vector memory, coping
|
|
from bit to logical requires only 70% of the time for copying from logical to
|
|
logical; and copying from logical to bit comes at a performance penalty of
|
|
150%. the package now contains further classes for representing logical
|
|
selections: 'bitwhich' for very skewed selections and 'ri' for selecting ranges
|
|
of values for chunked processing. All three index classes can be used for
|
|
subsetting 'ff' objects (ff-2.1-0 and higher).
