You may want to try something like this: x1<-rnorm(500) plot(x1) test<-seq(1987, 2002, by=1) test_2<-seq(2003, 2006, by=1) test<-format(c(test, test_2), width=5) xxx<-seq(1,500,length=length(test)) axis(1,at=xxx,labels=test,line=1,col=0)
You'll need to specify where you want the labels (in this code I do that with xxx). -tgs On Tue, Oct 19, 2010 at 12:55 PM, Simon Kiss <sjk...@gmail.com> wrote: > Dear colleagues, this seems like an easy problem, and I found some > suggestions which I've incorporated in the help list, but I can't quite get > it right. > I want to add a series of years to a second x-axis category label.
