Thanks Rich and Jim and apologies for omitting the line

x <- c(285, 43.75, 94, 150, 214, 375, 270, 350, 41.5, 210, 30, 37.6,
281, 101, 210)

But the fundamental problem remains that vertical spacing is not correct 
unless I waste a lot of image space at the top.

Dear Frank,
you can use grconvertY and grconvertX to convert from user coordinates
to inches etc and vice versa.
E.g.

lines(rep(.25*1500,2),grconvertY(grconvertY(par("usr")[3],"user","inches")+c(0,.1),from="inches",to="user"))

should produce a tick of 0.1 inches height, regardless of the actual
plot height.

Hope this helps.
