[R] Draw Overlapping Circles with shaded tracks

[Marc Girondot]

Another solution:

library("HelpersMG") plot(0:10,type="n",axes=FALSE,xlab="",ylab="", 
asp=1) ellipse(center.x = 3, center.y = 5, radius.x = 5, radius.y = 5, 
lwd=10, col=NA, border=rgb(red = 1, green = 0, blue=0, alpha = 0.5)) 
ellipse(center.x = 8, center.y = 5, radius.x = 5, radius.y = 5, lwd=10, 
col=NA, border=rgb(red = 0, green = 1, blue=0, alpha = 0.5))


(Without the graphic example, it is difficult to know what tit was 
supposed to do !)
