[R] funny arrows

[Ritter, Christian C SRTCL-CTGAS]

The result of 
> plot(c(-1,1),c(-1,1),type="n")
> arrows(0,0,1,1)
> arrows(0,0,0,0)
is not what I expected. The first arrow is drawn correctly. The second
does not collapse to a point but goes from (0,0) off to
(-infinity,infinity).
I guess something is divided by zero in the internal function.
