bitops
– implementing bitwise operationsBitwise operations on (the 32-bit) integers
Probably the smallest CRAN R package I maintain, the package has a long history, originating as S / S-plus extensions by Steve Dutky.
I got involved for the first time around 2004, and later became maintainer as Steve had moved on, and other CRAN packages depended on bitops
, see bitops on CRAN.
