Match how? Rows where intg equals rand_no at the same position? The rows of intg that are present somewhere in rand_no regardless of position? You need to be more specific.

They will have to reprocess the columns so that they can be read in by a function like read.table or read.csv. This will take some time and most won't bother-- they will just ignore your question. The best way to provide tabulated R data is to run your data frame through the dput() function and post that output. It won't look as nice, but any list user will be able to paste the code into their console and regenerate your table. -Charlie -- View this message in context: http://n4.nabble.com/extract-the-data-that-match-tp1558193p1558200.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
