According to ?arrows, it would seem that there is no provision to draw the arrow shaft and the arrow head using different line types with a single call to arrows(). To the extent that this represents the absence of a desirable feature (since you desire it), I would designate it as a bug. It can be done with two calls to arrows(), as follows: plot(1:10) arrows(4, 5, 6, 7, lty=2, length=0) arrows(5.99, 6.99, 6, 7, lty=1) Of course, the first could also be done using lines().
