r-bit64 4.0.5 S3 class for vectors of 64 bit integers
The bit64 package provides serializable S3 atomic 64 bit (signed) integers that can be used in vectors, matrices, arrays and
data.frames. Methods are available for coercion from and to logicals, integers, doubles, characters and factors as well as many elementwise and summary functions. Many fast algorithmic operations such as
order support interactive data exploration and manipulation and optionally leverage caching.
