search for: bitxor

Hi, I would like to xor (bitwise) two matrices filled with binary values (0,1). The result of such XOR is expected to be 0,1. But apparently neither of xor nor bitXor is working in this case. I got ": binary operation on non-conformable arrays" error message when I used xor (M1,M2) . The problem with bitXor(M1,M2) is that it just truncates the result into a vector rather than a Matrix. Do you know if there is a way to solve this issue (without needi...

I cannot find any R function or operator that performs a binary AND operation, as performed by Fortran built-in function "iand". Ideally either R operator "&" or "&&" should do that. But some tests proved they do not: > A<- 1 > B <- 2 > A [1] 1 > B [1] 2 > as.numeric(A&B) [1] 1 > as.numeric(A&&B) [1] 1 The binary

...D04943453FB8E5 at TFSMDMSG7> Content-Type: text/plain; charset="iso-8859-1" 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,...
