Please excuse me for asking such basic questions: Here is my code
y=c(1.21,0.51,0.14,1.62,-0.8,0.72,-1.71,0.84,0.02,-0.12) ybar=mean(y) ll=length(y); ybarv=rep(ybar,ll) x=1:ll plot(x,ybarv,pch=1) segments(x[1],ybar,x[ll],ybar)
What I get is a collection of small circles, with a segment "on top" of the circles, which is almost what I want. But I don't want the segment to be visible inside any small circle.
Is there an easy way to arrange for the segment to "lie behind" the pch=1 markers, as in hidden line removal, so that the circles remain with nothing inside them? I tried putting the segments command first, but then no segment appeared at all.
In general, is there a method of laying a drawing "on top" of another. I tried inserting add="T" as an argument to plot, and R objected strongly.
