[R] polygon angle option perpendicular to axis

[Peter Alspach]

Tena koe Simon

plot(1:10, 1:10, type='n')
polygon(c(2,3,6,8), c(2,5,5,3), density=20, angle=90)
polygon(c(2,3,6,8), 5+c(2,5,5,3), density=20, angle=0)

I don't understand your problem.  Perhaps if you "provide[d] commented, minimal, self-contained, reproducible code" it would help.

Subject: [R] polygon angle option perpendicular to axis

I am trying to use the angle option in polygon to create polygons filled with horizontal and vertical lines.  The polygons I am crating are irregular and it the angle function appears to set the angle of the shading perpendicular to the polygon sides rather than perpendicular to the axes.  Is there any way to set the angle relative to the axes rather than relative to the polygon sides?
