Dear Dan, The following also works:
> x <- numeric(0) > for (i in 1:5) x[i] <- i > x [1] 1 2 3 4 5 It's worth noting, however, that extending a vector in this manner can be very inefficient for large vectors, since the vector is recopied each time. If you can anticipate the number of elements (or place an upper bound on it), then it's better to do something like > x <- numeric(5) > for (i in 1:5) x[i] <- i I hope this helps, John -------------------------------- John Fox Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604 http://socserv.mcmaster.ca/jfox -------------------------------- > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Liaw, Andy > Sent: Tuesday, January 04, 2005 8:51 AM > To: 'Dan Bolser'; R mailing list > Subject: RE: [R] Adding values to the end of a vector? > > Is this what you're looking for? > > > x <- numeric(0) > > for (i in 1:5) x <- append(x, i) > > x > [1] 1 2 3 4 5 > > Andy > > > > From: Dan Bolser > > > > I want to add values onto the end of a vector, for example... > > > > x <- vector > > > > for (i in 1:5){ > > add_to_end_of_vector(i,x) > > } > > > > I just cant find the answer to this question! > > > > > > Sorry for such a basic question, I tried... > > > > x <- c() > > > > for (i in 1:5) x[length(x)] <- i > > > > but it didn't work. > > > > ______________________________________________ > > [email protected] mailing list > > https://stat.ethz.ch/mailman/listinfo/r-help > > PLEASE do read the posting guide! > > http://www.R-project.org/posting-guide.html > > > > > > ______________________________________________ > [email protected] mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! > http://www.R-project.org/posting-guide.html ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
