Well, the x limits likely don't extend that far. (You have noticed by
now that the axis extents are not the same as the sides of the
bounding box, right?) So set them:

hist(x,xlim=c(-4,4))

Or generically: hist(x,xlim=range(pretty(x))) tends to give the kind
of external axis that you're requesting. Less efficient use of space
though (since the axis is always longer than it needed to be).
