[R] Draw Overlapping Circles with shaded tracks

[John Kane]

That code nees the plotrix package:
library(plotrix)
pdf("circles.pdf")
plot(0:10,type="n",axes=FALSE,xlab="",ylab="")
draw.circle(4,5,radius=3,border="#ff0000aa",lwd=10)
draw.circle(6,5,radius=3,border="#0000ffaa",lwd=10)
dev.off()

 Hi Abou,
Without an illustration it's hard to work out what you want. here is a
simple example of two circles using semi-transparency. Is this any
help?

pdf("circles.pdf")
plot(0:10,type="n",axes=FALSE,xlab="",ylab="")
draw.circle(4,5,radius=3,border="#ff0000aa",lwd=10)
draw.circle(6,5,radius=3,border="#0000ffaa",lwd=10)
dev.off()
