Making the second layer of legend have full transparency seems to have fixed
the issue. My first layer has to have a white background because I have a
colored grid behind (sorry that didn't make it into my toy example).
I did try to use type=Xlib, but I get the error libpng warning:

I am trying to create a plot that has multiple plot characters for
each point (e.g. a point within a triangle, a triangle within a
square, etc). The workaround I have found to do this is by plotting
twice, as in this example:
x - c(1.1, 2.3, 4.6)
y - c(2.0, 1.6, 3.2)
plot(x, y)
points(x,y,
3 matches
