Dear Kirill, You are correct, that is a new bug introduced in PR16491. The appropriate fix and regression tests have been added via PR16885, which has been merged into trunk. I believe that means the fix will be released with R 3.3.1.
I checked your example and the second "match" now properly returns 1 with the patched code. Please have a look at https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=16885 http://developer.r-project.org/blosxom.cgi/R-devel/NEWS Thank you for your report. I hope the benefits of this speedup will eventually outweigh this unfortunate bug in my PR16491. Regards, Pete ____________________ Peter M.
