Andrew Gelman notes that the default graphics functions suck and that R has no real idea that all numbers aren’t conceptually signed floats. Gelman is told that the default graphics functions aren’t the ones we’re supposed to use these days (e.g. Trellis graphics a.k.a.
lattice and a bunch of stuff I’ve never heard of before today is preferable) and that R does have some idea that all numbers aren’t floats, but you have to convince R that the numbers you have aren’t floats, or something.
I think Gelman wins the argument by default.
