I can't get the points and "a" and "b" to render correctly (they are
squeezed into the axis) unless I make the height of the figure waste a
lot of space. I'd appreciate any ideas. The code is below. Thanks!
png('/tmp/z.png', width=480, height=100)
par(mar=c(3,.5,1,.5))
plot.new()
par(usr=c(-10, 410, -.04, 1.04))
par(mgp=c(1.5,.5,0))
axis(1, at=seq(0, 400, by=50))
axis(1, at=seq(0, 400, by=25), tcl=-.25, labels=FALSE)
title(xlab='Mean Count')
points(x, rep(-.02, length(x)))
lines(rep(.25*1500, 2), c(-.04, .04), col='blue')
lines(rep(.196*1500, 2), c(-.04, .04), col='blue')
text(.25*1500, .07, 'a', col='blue')
text(.196*1500,.07, 'b', col='blue')
dev.off()
It works if I use height=350.
