ggquiver 0.5.0

  • Fixed automatic vecsize grid detection incorrectly rescaling arrows for irregularly spaced data (e.g. GPS coordinates) whenever the x- and y-spacings happened to coincide.
  • Automatic vecsize grid detection now warns instead of erroring when a grid size can’t be determined (e.g. a single data point), leaving arrows unscaled.
  • geom_quiver() now hints to use coord_fixed()/coord_equal() if needed (#10).
  • Legend keys now show an arrowhead, matching the arrows drawn in the panel.
