Hello, I submitted this bug report to r-core and got a rejection saying I should post to r-help. This is my first time ever submitting a bug report, so forgive me if I'm using some wrong format. So, here's my bug report: Component: Graphics OS: Mac OS 10.5.8, X11 XQuartz 2.5.0 Summary: In the symbols function of the graphics package, scaling of the y-axis is wrong, causing symbols

Hi, I don't think this is a bug, but I thought I'd mention it in case others think it is not correct... I guess it is probably just a rounding error. If I use symbols() to draw some circles, any circle with radius of zero gets drawn as a small circle. As an example: postscript(file="test.ps") symbols(1:9, rep(2,9), circles=seq(from=0.05, to=0.0, length=9),

I'm new to R and i'm having some trouble with a bubble chart. Basically I have 3 series (a,b,c), but the third one is a binnary variable (assumes only 0 or 1 to the entire data). How can I use these binnary information to make 2 different colours in a bubble chart?. I.e., I'm using this code: symbols(inv$a, inv$b, circles=radius, inches=0.35, fg="white", bg="red",

I have a diagram to be included in latex, where all my figures are .eps graphics (so pdflatex is not an option) and I want to achieve something like the following: three concentric filled circles varying in lightness or saturation. It is easiest to do this using transparency, but in my test using the postscript driver, the transparent color fills do not appear. Is it correct that postscript()

Hello, I am not able to plot a circle of a given radius using symbols(). In the example below, the circle appears too large: plot(0, 0, xlim = c(-1, 1), ylim = c(-1, 1)) symbols(0, 0, circles = 1, inches = FALSE, add = TRUE) What's happening? Ery

Dear friends, I was drawing a circle with centrum in (1,-1) and radius 5 to show my girl that the line y=3*x+1 goes through (1,4) and (-2,-5) of the circle, but on Windows XP, R 2.20 the drawing was not good at all, and the known solutions were not shown in the graph. I guess I got it wrong? Is this use not intended ? Best wishes Troels Ring, MD Aalborg, Denmark

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 circle isn't radius 40; it is closer to 15... I

Dear list, I am trying to program semi-random movement within a circle, with no particles leaving the circle. I would like them to bounce back when they come to close to the wall, but I don't seem to be able to get this right. Would somebody kindly give me a hint ? This is my code so far, the particle starts at some point and moves towards the wall, but I don't get the "bouncing

Hi, I have spatial data for plants that I would like to plot according to its radius using sysmbols(). Also I would like to color the circles according to an individual's age using heat.colors(17) [ages within the whole data set range from 0:16]. I have not found an easy way to assign ages (=a) a specific heat.color. Any suggestions? Thanks, Patrick x <- c(1,3,4,6,7,3,2,8,3,6,5,5) y

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)

Hi, I came across with a tiny problem. E.g.: pdf() plot(1:5) points(2, 3, cex=10, pch=21, bg="grey", lwd=0.3) points(2, 4, cex=1, pch=21, bg="grey", lwd=0.3) dev.off() If I execute this I'll get a nice PDF. Fine. But I want to edit this PDF with let's say by using Adobe Illustrator. If I try to open it Illustrator shows up an error message: Missing Type 1 fonts

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 =

Hello R-gurus, I'm trying to adjust different growth curves to a rather extensive dataset. I wrote up a function to go through all of them, but am encountering a problem : among the more than 1000 curves I have, obviously for some of them I encounter conversion problems. I'd like for my function to keep going to the next curve and store the fact that for curve number X I had a convergence

Hi, I'm fitting a standard nonlinear model to the luminances measured from the red, green and blue guns of a TV display, using nls.

Hi all, I'm trying to use symbols() to draw a circle of a given radius at a given position onto a filled.contour() plot. The commands I issue are: > filled.contour(y,x,z,levels=seq > (0.02,1.0,len=50),color.palette=colorRampPalette(c > ("blue","yellow","red")),title=title(main="",xlab="",ylab="")) >

I want to add a line that represents the relationship between x and y to a strip chart, I've tried the following functions: par(new=TRUE) points(x,y) lines(x,y) but nothing works, I get the strip chart but line doesn't show up. Here is my function: stripchart(hydfin$exp ~ hydfin$alt, vert = TRUE, pch = 1, method = "jitter", jit = 0.05, xlab = "Elevation", ylab =

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:

Hello, I'm a new user to R so apologies if this is a basic question, but after scouring the web on information for summary.formula, I still am searching for an answer.
