Yes, it works. Thanks! I see that the row names are now: 1, 1.1, 1.2, 1.3, 1.4, 1.5, 2, 2.1 ..... It does not bother me, but is this going to be a problem later on? I need to further manipulate the first 2 columns. This is what I would like to do: (1) the first column should have: "doc_date", "doc_type", "doc_id", "title", "author", "author_cat" repeated down the data frame. You can see that there are 6 strings, one for each of the 6 replicated rows. (2) Then I need to replace in the second column all values except the one on the 3rd replication. Thanks a bunch! This is my dissertation work, so very, very important for me :-) Best, Henri-Paul -- Henri-Paul Indiogine Curriculum & Instruction Texas A&M University TutorFind Learning Centre Email: hindiog...@gmail.com Skype: hindiogine Website: http://people.cehd.tamu.edu/~sindiogine ______________________________________________ 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.
