Hi, is there any function that would allow me to read in a string of 1 or 0's (which can be very long) and then convert that to a binary number so that I cn do logical operations (as well as operations such number of 1's or number of 0's) Currently I do it by creating a vector and have written functions to do what I need - I was wondering whether there was anything native to R for this type of thing (bitset) Thanks, ------------------------------------------------------------------- Rajarshi Guha <rxg218 at psu.edu> <http://jijo.cjb.net> GPG Fingerprint: 0CCA 8EE2 2EEB 25E2 AB04 06F7 1BB9 E634 9B87 56EE ------------------------------------------------------------------- Q: What's yellow, linear, normed and complete?
