You could also read them in so that the 1 and 0 are in one field and specify that this column is a character, and then use strsplit() to split them up: > x <- "1010101110011110011110011100111100110" strsplit(x, split="") [[1]] [1] "1" "0" "1" "0" "1" "0" "1" "1" "1" "0" "0" "1" "1" "1" "1" "0" "0" "1" "1" [20] "1" "1" "0" "0" "1" "1" "1" "0" "0" "1" "1" "1" "1" "0" "0" "1" "1" "0" Cheers, Rainer > > > Regards > > ______________________________________________ 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. - -- Rainer M.
