I couldn't find any specific examples in the R manual.  The problem is I don't think that is correct, as the histogram disappears at breaks = 1550.

Hi Julie,
Not quite. I would guess:

breaks=0:170
breaks=seq(0,170,by=2)
breaks=seq(0,170,by=5)

I'm not surprised that something went wrong with 1550 breaks.
