similar to: shade overlapping portions of circles (or other shapes)

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()

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 without the image. with

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 =

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() On Friday, December 29, 2017, 6:06:32 PM EST, Jim Lemon <drjimlemon at gmail.com> wrote:

Dear All: Thank you very much for 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)

I want to shade the area under the curve of the standard normal density. Specifically color to the left of -2 and on. How might i go about doing this?

Greetings. I'm trying to understand a problem on a Dell Laptop. Details below, also uploaded the R working example that I pasted below. http://pj.freefaculty.org/scraps/testSymbols.R > sessionInfo() R version 2.15.1 (2012-06-22) Platform: x86_64-pc-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5]

Hi, I'll try to keep my question brief and to the point, to anyone who helps 'THANK YOU!' I want to get a circle/ring/buffer or some other form of drawn line around certain points on a x,y plot, the points usually don't form a circle, often they form a 'wobbly' shape, so ideally I'd like something that follows the shape the points make. I'll start by explaining

Hi, I am using wireframe with shade=T and I would like a colour key that matches the colours produced with the option shade=T. How do I do this? Thanks, Karim

Speaking of optimization and speeding up R calculations... I mentioned last week I want to speed up calculation of generalized inverses. On Debian Wheezy with R-2.15.2, I see a huge speedup using a souped up generalized inverse algorithm published by V. N. Katsikis, D. Pappas, Fast computing of theMoore-Penrose inverse matrix, Electronic Journal of Linear Algebra, 17(2008), 637-650. I was so

Is there a function that can shade the region between two arbitrary curves? For example, how can I fill in the area between these two plotted curves? > x <- 1:10 > y <- x + rnorm(10) > z <- x + 10 + rnorm(10) > plot(x, y, type = "l", ylim = c(0,20)) > lines(x, z) I would appreciate any help. David

Hi, want to shade the area between dotted lines: x=c(1,5);y=c(1,5) plot(y~x, type='n') abline(v=c(2,3), lty=2) sometnig simple needed. tried with polygon.... thx, robert -- View this message in context: http://r.789695.n4.nabble.com/shade-area-between-ablines-tp2537352p2537352.html Sent from the R help mailing list archive at Nabble.com.

I am using wireframe from the lattice package, with the shade option set to TRUE. When I output to PDF or Postscript, a line gets drawn around each polygon of my surface which causes ugly Moir? effects and doesn't make sense in my application (think the plot of Maunga Whau--gridlines don't make sense). This does not happen when I display on the screen-- then I just get the surface as

Hi, Thanks for all the great work on compiz, you guys have been great, the shade function works wonderfuly. There's a minor, or not so minor, thing I noticed, if I try to shade an application which minimizes to systray, it shades until it leaves a titlebar-sized artifact on the screen, then I can only activate it again after clicking the notification area icon again. Best regards, Diogo

Hi David et all, Just to let you know that the new "window shade" effect, although extremely buggy at the moment, is simply *wonderful*. Thanks.

Dear list members, How can I shade the background area of a zoo time series object between specific dates? eg. library(tseries) library(zoo) SP500<-get.hist.quote("^GSPC", start = "1990-01-01", quote = "Close") plot(SP500) How can I produce the same plot but with a (say) red background between 2007-04-12 and 2008-05-14 ?

I'm writing to ask for a policy exception, or advice on how to make this package CRAN allowable. http://rweb.quant.ku.edu/kran/src/contrib/portableParallelSeeds_0.9.tar.gz Yesterday I tried to submit a package on CRAN and Dr Ripley pointed out that I had not understood the instructions about packages.

Hi all, I've got this graphics question which really should be easy. I want to shade an area between bounds under a curve. A suitable beginning seems to be the following: > plot(dnorm,-4,4) > segments(-4,0,4,0) > segments(-2,0,-2,dnorm(-2)) > segments(2,0,2,dnorm(2)) It is the area between -2 and 2 which I want to shade (or something similar). Hints anyone? Robert

In our recent workshop on "Multilevel Modeling in R" we discussed handling data for multilevel modeling. An classic example of such data are test scores of students grouped into schools. We may wish to model the scores as functions of both student-level covariates and school-level covariates. Such data are often organized in a multi-table format with a separate table for each level of
