Hi, I would like to be able to shade the background of part of an axis. To illustrate, consider the following code:
par(xaxt="n") x=1:10 y=rnorm(10,0,1) plot(x,y,type="l",xlab=NA) mtext(text=LETTERS[1:10], side=1, at=1:10) How can I make the background behind, say, "G H I" on the x-axis red? I have tried using "polygon," but cannot seem to get it to plot outside the graph borders. Any suggestions?
