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" Cheers, Cristián. -----Mensaje original----- De: David Winsemius [mailto:dwinsem...@comcast.net] Enviado el: Martes, 03 de Agosto de 2010 05:26 p.m. Para: Cristian Montes CC: Henrique Dallazuanna; r-help Asunto: Re: [R] concatenate values in the vector On Aug 3, 2010, at 5:17 PM, Cristian Montes wrote: > Even shorter is > > x<-c("a","b","c","d") > paste(x, sep="+") [1] "a" "b" "c" "d" Except for the fact that it does not deliver what the OP appeared to be asking for. The paste function is vectorized, so if you give it a vector of length 4, it returns a vector of length 4. What was requested, at least up to the ambiguity left by no quotes around the requested ouput, was a single string. -- David. > Cheers, > > Cristian Montes > > -----Mensaje original----- > De: r-help-boun...@r-project.org [mailto:r-help-boun...@r- > project.org] En nombre de Henrique Dallazuanna > Enviado el: Martes, 03 de Agosto de 2010 04:37 p.m. > Para: phoebe kong > CC: r-help > Asunto: Re: [R] concatenate values in the vector > > Try this: > > paste(x, collapse = '+') > > On Tue, Aug 3, 2010 at 5:34 PM, phoebe kong <sityeek...@gmail.com> > wrote: > >> Hi all, >> >> Is there a function that allow me to concatenate each value in a >> vector to a string? >> >> x<-c("a","b","c","d") >> >> output string = a+b+c+d >> >> Thanks, >> phoebe >> >> [[alternative HTML version deleted]] >> >> ______________________________________________ >> 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. >> > > > > -- > Henrique Dallazuanna > Curitiba-Paraná-Brasil > 25° 25' 40" S 49° 16' 22" O > > [[alternative HTML version deleted]] > > ______________________________________________ > 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.
