It's not a bug in r-bc, it's a misfeature (?) in bc. It has to do with the 'scale' parameter in bc (which gets set to 100 explicitly by r-bc, but would be set to 20 in any case by the use of the '-l' option to bc) http://superuser.com/questions/31445/gnu-bc-modulo-with-scale-other-than-0 http://en.wikipedia.org/wiki/Bc_programming_language http://www.linuxquestions.org/questions/programming-9/bc-using-l-messes-up-modulus-331003/ a workaround; source(http://r-bc.googlecode.com/svn/trunk/R/bc.R;) bc(scale=0; 9%2) [1] 1 __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
