Ok, sorry, I misinterpreted the question! Here is the right solution x <- c("a", "b", "c", "d", "e") z <- x[1] for (i in 2:length(x)) { z<- paste(z, x[i], sep = "+") } print(z) [1] "a+b+c+d+e"
Or paste(x, collapse = '+') which was the solution that was in the message you originally replied to. ______________________________________________ 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.
