Hi! Thanks for this great package. geom_quiver() is returning the following warning (with no output) when I try to reproduce the examples in the package: 

Warning message:
Computation failed in `stat_quiver()`:
argument is of length zero

I noticed the pkgdown documentation is showing the same error.

Reprex:

library(ggplot2)
library(ggquiver)
library(dplyr)

expand.grid(x=seq(0,pi,pi/12), y=seq(0,pi,pi/12)) %>%
  ggplot(aes(x=x,y=y,u=cos(x),v=sin(y))) +
  geom_quiver()

Thanks!
