[R] Functions for bit manipulation in R/Splus

[Dutky, Steve]

Hi,
I primarily use Splus for analysing TCP/IP traffic at the packet level.

Several years ago, I hacked together functions using the .C call for bit
operations:

bitAnd,  bitOr, bitFlip, bitShiftL, bitShiftR, bitXor and crc(char).


Are there any more standard alternatives for these?

If not, and, if any there is any interest, I would  be happy to help package
what I have for distribution.


Additionally, I would interested in hearing offline from anyone using
R/Splus communication network analysis.


Thanks, Steve Dutky
