I'd like to paste a zodiac sign on a graph, but it only prints it when I add another unicode ( \u3030) to the desired \u2648 - why? See the examplecode (compare the orange with the skyblue): plot(c(-1,1),c(-4,-2),type="n") text(x=0,y=-3.0,labels="\u2648 \u3030",cex=2.3,col="skyblue") text(x=0,y=-3.2,labels="\u2648",cex=2.3,col="orange")

I estimate some parameters and I want to print them (pretty) on my plot: # somehow estimated parameters z<-c(1.543523e+00, 1.23453e+00, 3.454000e+00) x<-seq(-1,1,length=100) plot(x,z[3]*x^2+z[2]*x+z[3],type="l", main="My nice plot of the estimated function") zs<-format(z,digits=4,scientific=FALSE,trim=TRUE) text(-0.9,7,expression(1.54*x^2)) # is

I want to plot the results of today's elections in Austria in this typical 180?-piechart (and not 360?). Unfortunantely pie() has just an argument "init.angle" and no "end.angle". Perhaps you know a workaround. Thomas

Hi I want to draw sth in a pdf file with a predefined defined size. Say a 5cm x 3cm rectangle (a ruler): pdf("rect.pdf", paper="a4") plot(c(1,5,5,1,1),c(1,1,3,3,1),asp=1,axes="n") dev.off() but how do I fix that one unit is 1cm? Thanks thomas

Is there a R-package with a function that returns me the timezone, if I hand over longitude and latitude? I know online services like http://ws.geonames.org/timezone?lat=-38.01&lng=147 and http://www.earthtools.org/webservices.htm#timezone and wodner if this exists for R too. Thanks for helping, thomas

Hi, could it be that the text() fuction gives different output for normal png() and CarioPNG()? See the following example and the attached images: the font=2 and font=3 seem to be exchanged! Thanks for help, Thomas CairoPNG("Test-cairo.png",width=750,height=690) #png("Test-normal.png",width=750,height=690) plot(1,1,type="n",main="normal")

I have integers and I want R to give them back/output as Roman numerals: s=c(7,17) format(s,roman=T) is obviously wrong. Is there any other way/function to do this? Thanks, Thomas

I want to plot something (eg a circle) with a fixed ratio of the x and y axis, or (even better) with a fixed size when I print it. Output should then be a circle (actually it'll be someting more complicated) with radius 5cm and not an ellipse. I'm _sure_ this is not new, but after looking 45min for a solution, I post here... Thanks for help Thomas

I cannot access internet through R. My IT-guys told me that I should set the proxy and the port and then everything will be fine. Where can I set them? I use R 2.6.2 under Windows 2000 and these settings are those of the Internet Explorer (no password). I read http://cran.at.r-project.org/bin/windows/base/rw-FAQ.html#The-Internet-download-functions-fail_002e but staring R by "C:\Program

I want to create a open/high/low/last plot of intraday data. I try to use the function plotOHLC from the tsteries package.

I want to draw a little subplot ("overview") into my detailed plot.

I want to write something like (LaTeX style) b_{norm}=\frac{F\prime(0)}{R\prime(0)} how do I add the "prime" (first derivative) to a R-plot? The help of "plotmath" just talks about "partialdiff". Can you complete this command? text( 30,0.05,labels=expression(b[plain("norm")]==frac(F(0),R(0))) ) Thanks, Thomas

The filled.contour function gives me some strange output. What did I do wrong? x=seq(0,1,length=10) y=seq(0,1,length=10) z=array(rnorm(100),dim=c(10,10)) filled.contour(x,y,z) lines(0.4,0.8,type="p") abline(v=0.4,lty="dashed") the x-cooridnate of the line and the point is 0.4, but it's slightly above. This problem just appears with "filled.contour", so I guess

Hi, on http://cran.at.r-project.org/bin/windows/base/rw-FAQ.html#Where-can-I-find-the-latest-version_003f it says: ... The current release is distributed as an installer `R-2.6.1-win32.exe' of about 30Mb. ... however I find this file as well: http://cran.at.r-project.org/bin/windows/base/R-2.6.2-win32.exe I guess that in the FAQ it should read as 2.6.2 Have a nice holiday, Thomas

The characteristic function is the inverse Fourier transform of the distribution function. The characteristic function of a normaly distributed random variable is exp(-t^2/2). x=seq(-2,2,length=100) fft(pnorm(x),inverse=T)/length(x) exp(-x^2/2) Why aren't the inverse fft and the mentioned function the same? Thanks for help, Thomas

Hi, text()'s pos does handle more dimensional labels, while adj does not - or how can I pass an array to text() and use the adj argument (skyblue text)? plot(-1:1,-1:1) text(c(0,0),c(0,0),c("a","b"),pos=c(1,2),col="red") text(c(0,0),c(0,0),c("a","b"),adj=cbind(c(1,2),c(1,1)),col="skyblue") Thomas

Hi, how can I reverse the radius axis of plotrix's polar.plot function? Perhaps this sounds strange, but I use the radians for angles as well: In the center is zenith and the corresponding angle is 90?, not 0.
