...all of you. I just have one more thing. Is there a way to fill the borders with small dots, may be different sizes. I tried to do it, but it looks ugly. Here what I tried: library(plotrix) plot(0:10, 0:10, type="n",axes=FALSE,xlab="",ylab="") #### 0:5, draw.circle(4,5,radius=3,border="#ff0000aa", lwd=75) draw.circle(4,5,radius=2.50,border="red",lty=3,lwd=3) draw.circle(4,5,radius=2.55,border="red",lty=3,lwd=3) draw.circle(4,5,radius=2.60,border="red",lty=3,lwd=3) draw.circle(4,5,radius=2.65,border="red",lty...

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...

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 install.packages(&...

Hello everyone I hope Im not bothering you all again. I have just begun to use R and so Im not yet familiarized with it.. I ve got an assignment which consists in calculating the area of a circle given a certain radius and center using the monte carlo method, which means that I have to plot a circle given its parameters. Limit the area inside it...with as many sample points as possible...and all of this inside a nxn size window, which could be 1x1, or any size actually. I wonder how I cou...

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...

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-tp42787...

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...

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() Jim On Fri,...

Dear R experts, I am plotting the population 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...

how to draw a circle (e.g. radius=10cm) of one point? And how to choose these points in the circle? Thanks! [[alternative HTML version deleted]]

Hi there, I tried to add a few circles on an existing figure using the following codes grid.circle(x=0.5, y=0.5, r=0.1, draw=TRUE, gp=gpar(col=5)) grid.circle(x=0.5, y=0.5, r=0.3, draw=TRUE, gp=gpar(col=5)) grid.circle(x=0.5, y=0.5, r=0.5, draw=TRUE, gp=gpar(col=5)) points(0.5, 0.5, col = 5) # centre of the circle , but al...

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 c...

hi: where would I find facilities to draw circles, ovals, and semicircles? (or should I construct them myself using curve?) regards, /ivo

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-m15...

for a simple scatterplot: plot(X ~ Y, type = 'p', col = 'red') this produces red-edged circles, but I want to fill in the circles. can this be done? I checked '? plot' already but couldn't find what I was looking for. cheers -- View this message in context: http://r.789695.n4.nabble.com/scatterplot-with-filled-circles-tp3044690p3044690.html Sent from the R help mailin...

R-listers, Given a polygon and a circle 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...
