Here is one approach (you can adapt as needed): library(TeachingDemos)
par(mfrow=c(4,2)) plot(1:10) plot(10:1) plot(c(1:5,5:1)) plot(c(5:1,1:5)) tmp <- cnvrt.coords(1,0, input='fig')$usr # get right end coord tmp2 <- cnvrt.coords(0,NA, input='tdev')$usr # get left end par(xpd=NA) # turn off clipping segments(tmp$x,tmp$y,tmp2$x,tmp$y, col='blue') hist(rnorm(10)) hist(rnorm(100)) hist(rnorm(3)) hist(rnorm(10000)) Hope this helps, -- Gregory (Greg) L.
