Such a function is already in gmp: factorize(n), and it works with fairly large numbers: >library(gmp) >factorize(12345678987654321) Big Integer ('bigz') object of length 13: [1] 2 2 2 2 5 7 11 73 101 109 109 137 167 Success, Frank ------ Franklin Bretschneider Dept of Biology Utrecht University brets...@xs4all.nl ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
