Try this instead: yourframe[,30:51] <- cbind( newcolumn,yourframe[,30:50]) Adjust column names after via: names(yourframe) [30:51] <- c(newcolname,names(yourframe[30:50]) Cheers, Bert On Mon, Aug 1, 2011 at 10:10 AM, Sarah Goslee <sarah.gos...@gmail.com> wrote: > x <- cbind(x[,1:29], newcolumn, x[,30:ncol(x)]) > > On Mon, Aug 1, 2011 at 12:59 PM, Bansal, Vikas <vikas.ban...@kcl.ac.uk> wrote: >> Dear all, >> >> I have a very simple question.I have data frame of 50 columns and i want to insert a column in 30th position.But i do not want to delete that column.Is it possible to include a column in between, so that new values are in 30th column and 30 th column is now 31st and 31st is 32nd......so on and 50th column is 51st..?I will be very thankful to you. >> >> > > > > -- > Sarah Goslee > http://www.functionaldiversity.org > > ______________________________________________ > 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. > -- "Men by nature long to get on to the ultimate truths, and will often be impatient with elementary studies or fight shy of them.
