%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).
