 Description: GNU R class for vectors of 1-bit booleans
  This GNU R package provides bitmapped vectors of booleans (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

  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).
