[R] transparent concentric circles
I have a data set which I would like to plot as a set of concentric circles. The data represent a count of the number of characteristics shared by various elements - an example would look like this: 1 100 2 75 3 50 4 25 I.e. all four sets share 25 characteristics, three of them share 50 characteristics, and so on. I would like to plot these as concentric circles, with the circle size preferentially being proportional to the size of the number of elements (this is not a must, however). I would also like the colors of the circles to become stronger/deeper as we progress to the innermost circle (which would be the one containing the number of characteristics shared by all four). Can somebody point me to what I can use to do this? Thanks!

Can somebody point me to what I can use to do this? help.search(circle)? Have you tried any of those? Specifically: plotrix::draw.circleDraw a circle. shape::filledcircle adds colored circle to a plot grid::grid.circle Draw a Circle - assuming you have those packages loaded...

Hi Karin, As Barry noted, you can use draw.circle in the plotrix package: plot(0,xlim=c(-100,100),ylim=c(-100,100),type=n,axes=FALSE, main=Set intersection plot,xlab=,ylab=) par(xpd=TRUE) draw.circle(0,0,100,col=#ffccff) draw.circle(0,0,75,col=#ff99ff) draw.circle(0,0,50,col=#ff44ff) draw.circle(0,0,25,col=#ff00ff) par(xpd=FALSE) These aren't transparent, but if you really need transparency, just add the alpha level to the colors. Look at boxed.labels to label the circles.
