How to draw holes generated by gpclib using plot function
Hi.
I've tried to create a polygon with one hole by gpclib using following
example script.
holepoly <- read.polyfile(system.file("poly-ex/hole-poly.txt", package
="gpclib"), nohole = FALSE)
area.poly(holepoly)
plot(holepoly,poly.args=list(col="red",border="blue"))
And I noticed plot function couldn't draw polygons with holes correctly.
Does anyone know how to solve this situation?
Regards.
