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 t...

draw a circle with a gradient fill
Hi all,I would like to draw a simple circle where the color gradient follows the rule color = 1/(r^2) where r is the distance from the circle. I would also like to add a color bar with values going from -40 to -110 (and associate those with the color gradient that fills the circle). So far I experiemented with draw circle

monte carlo method for circle area
...could be 1x1, or any size actually. I wonder how I could just limit the area inside the circle..that would be great help for me. Some of you have given me several suggestions about plotting a circle using some built-in functions but I wonder if its suits my problem since I have to somehow limit the circles inner area. thanks a lot __________________________________________________________________ Roxana Bravo ICQ#: 14040506 _________________________________________________________________ --------------------------------- O melhor e-mail gratuito da internet: 6MB de espaço, antivírus, ace...

Draw Overlapping Circles with shaded tracks
Dear All: I am wondering if there is a way in R to draw these two circles with shaded tracks in both circles using R, and make both circles uncovered. I am trying to make it in MS words, but I could not. Your help will be highly appreciated. In my previous post I added the image of the two circles, but the post never published. I just thought to resent the post again w...

RGL- Drawing Circle
hi, i want to draw a simple circle by using 3d package RGL. i think i can use the command rgl.lines by studying the code from: http://www.swiftless.com/tutorials/opengl/circle.html but is there a faster and easier way to do it?? graham -- View this message in context: http://r.789695.n4.nabble.com/RGL-Drawing-Circle-tp4278717p4278717.html Sent from the R help mailing list archive at

Very inaccurate circles
Hello, Please take a look at the attached plot and let me know if this is normal. The circle has radio I am using R 2.9.2 inside OS X Leopard. The plot was generated with: png('bizarre_circle.png') plot(c(-5,0,0,5), c(0,5,-5,0)) symbols(0,0, circles=c(sqrt(25)), inches=FALSE, add=TRUE) dev.off() If I resize the x11's plot window I can manage to make the circle pass through all the points but it's the first time I have to do this. I understand this may be happening because of the method to draw circles. I googled and found this other m...

Draw Overlapping Circles with shaded tracks
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.

How to add circular text for a graph with concentric circles
...lation of students who live in a city, and in successive circular bands made of the contiguous districts that surround the city. This is a stylized figure, where I specify the area of each successive circle based on the cumulative population of students. I want to compare two sets of concentric circles across different populations - such as 'All students' and 'Private students' (those attending private school) by using the same colours and the same dimension of the outer circle. I have attached the .pdf file with the output, and the R code to generate the first set of circles....

'symbols' not plotting correct circle radii
Hi there. I have been plotting some circles using 'symbols', with radii representing my data, but the radii looked incorrect. It seems to happen with a single circle too: Symbols ( 0, 0, circles = 40, xlim = c(-40, 40), ylim= c(-40, 40)) If I put a ruler up to my monitor (technology!) to compare the radius with the axes, the cir...

shade overlapping portions of circles (or other shapes)
I'm making some illustrations and it would be convenient to automatically shade the overlapping portions of circles. These illustrations are for Social Choice theory, a field in political science and economics. I've wrestled together some examples so you can see what I mean, but have not mastered the "color overlapping sections" problem (as you will see): http://pj.freefaculty.org/scraps/t-m15g....

Area of overlap between polygon and circle
...e defined by its center coordinates and a radius, I would like to calculate the area of overlap. I know that I can create a polygon from the circle and then use available packages to get the area of the intersection. However, because the polygon is of a fixed size and I will be doing this for circles of varying sizes, I'm concerned about maintaining the appropriate amount of resolution with larger circles. If there was already a package that did the above calculation without the creation of a circle polygon and would thus give an exact area, that would be preferred. I have searched t...
