search for: dec2bin

Hello, I just want to ask if there is any function that can convert decimal number to binary vector. Thanks a lot. Haiyong

Hi, The latest version of R had some changes to functions "readbin() and writeBin() [which] now support raw vectors as well as filenames and connections.". As a result I am working on retiring "raw2bin" and "bin2raw" functions from "caTools" package which do exactly the same. Thanks to Prof. Ripley for bringing this change to my attention. Which brings me

Hello, we need to convert a logical vector to a (decimal) integer. Example: a=c(TRUE, FALSE, TRUE) (binary number 101) the function we are looking for should return dec2bin(a)=5 Is there a package for such a function or is it even implemented in the base package? We found the hexmode and octmode command, but not a binmode. We know how to program it ourselves however we are looking for a computationally efficient algorithm. Martin and Stefan
