Question

I have a histogram from a list d of values that I make by simply typing

hist(d)

And this is what I get:

Answer 1

Two suggestions:

#See if this is sufficient:
hist(...)
box()

#If not, try custom axes:
hist(..., xlim = c(-.5, .5), axes = F)
box()
axis(1, seq(-.5, .5, length = 6))
axis(2, seq(0, 30, by = 5))
