Hi all,
R> seq(-.4, .8, length=7)
[1] -4.000000e-01 -2.000000e-01 5.551115e-17 2.000000e-01 4.000000e-01
[6] 6.000000e-01 8.000000e-01
Well that may not be a "bug", but it has this unfortunate consequence:
R> pretty(c(-.4,.8))
[1] -4.000000e-01 -2.000000e-01 5.551115e-17 2.000000e-01 4.000000e-01
[6] 6.000000e-01 8.000000e-01
And thus my plot axes look funny unless I apply zapsmall:
R> plot(c(-.4,.8), c(-.4,.8), axes=F)
R> axis(1, at=pretty(c(-.4,.8))) # Yuck!
R> axis(2, at=zapsmall(pretty(c(-.4,.8)))) # Better!
So here's my simple suggestion: change the last line of pretty() from:
seq(z$l, z$u, length = z$n + 1)
to:
zapsmall(seq(z$l, z$u, length = z$n + 1))
I'm running R-1.5.0 on platform sparc-sun-solaris2.6.
