Hi Ryan, The issue is the plotting region is slightly padded. The easiest option, I think, would be to clip() it. I have a general sense that one of the par() options would let you adjust the padding to 0, but I could just be imagining that (anyone else??). Anyway, here are some options:
### plot(0:5, seq(0, 10, 2), axes=FALSE) axis(1, at=c(0,1,2,2.5,3,4,5), pos=0) axis(2, at=seq(0, 10, 2), pos=0) ## using clip and abline clip(0, 5, 0, 10) abline(h = 1:5) dev.new() plot(0:5, seq(0, 10, 2), axes=FALSE) axis(1, at=c(0,1,2,2.5,3,4,5), pos=0) axis(2, at=seq(0, 10, 2), pos=0) ## using lines, but without retyping as much sapply(1:5, function(y) lines(c(0, 5), c(y, y))) ## or even easier, getting the same thing with segments segments(0, 1:5, 5, 1:5) HTH, Josh On Tue, May 3, 2011 at 10:26 AM, Ryan Utz <utz.r...@gmail.com> wrote: > Well... that could work.
