Dear all, I'm looking for an alternative way to replicate the "2," string for an x number of times, and end up with one string containing "2," x times. I can partly achieve this using replicate().> y <- rep("2,", times=3) > y[1] "2," "2," "2," The output that I am looking for is, however, "2,2,2,". I also tried to append(), with similar (unsatisfactory) results.> z <- for (i in 1:3) {+ z <- append(z, y[i])}> z[1] "2," "2," "2," Could anyone suggest how "2," can be replicated to "2,2,2,"? Thank you, Liviu -- Do you know how to read? http://www.alienetworks.com/srtest.cfm Do you know how to write? http://garbl.home.comcast.net/~garbl/stylemanual/e.htm#e-mail
have a look at ?paste(), e.g., paste(rep(2, 3), collapse = ",") and if you need a comma at the end, then you can again use paste(), paste(paste(rep(2, 3), collapse = ","), ",", sep = "") I hope it helps.

See ?rep and ?replicate.
Thanks all. All solutions are usable. These two I received off-list:> toString(paste(rep("2",3), sep=","))[1] "2, 2, 2" and> paste(rep("2,",3),collapse="")Liviu On Wed, Dec 3, 2008 at 9:14 AM, Dimitris Rizopoulos <d.rizopoulos at erasmusmc.nl> wrote:> have a look at ?paste(), e.g., > > paste(rep(2, 3), collapse = ",") > > and if you need a comma at the end, then you can again use paste(), > > paste(paste(rep(2, 3), collapse = ","), ",", sep = "") >
