similar to: text with greek letters

Hi, I desperately try to do s.th. like m=1.23455 sig=0.84321 plot(1,1) text(0.8,1,sprintf("<Sigma>=%1.2f?%1.2f",m,sig)) where actually the greek letter should appear for Sigma. I have tried all sorts of combinations with expression and paste etc. but could not work it out. Maybe someone has an idea and can help me. Thanks a lot+ Thomas

Dear Everyone, I am using R 2.6.2 on my Redhat AS4. I installed the RPM offered on the cran website. I would like to use R from my bash console with the following command: /path/to/R --vanilla --slave --args < /data/myscript.R this script invokes a range of functions and tools, among others to process a bunch of raster images in a loop using GDAL. The thing is that releasing this command in

I am having troubles in fitting functions of the form y~a*x^b+c to data, for example x<-c(0.1,0.36,0.63,0.90,1.166,1.43, 1.70, 1.96, 2.23) y<-c(8.09,9.0,9.62,10.11,10.53,10.9, 11.25, 11.56, 11.86) I tried for example with nls, which did only work with really good initial guessed values. Any suggestion, what I should use? Thanks a lot Thomas [[alternative HTML version deleted]]

Hello all, I'm trying to use liboggz to parse and display Ogg media files. I'm wondering what the return value of oggz_tell() actually is and how is one supposed to use it. The documentation says that oggz_tell() returns "the current offset of oggz". This sounds like it would be basically the file position indicator, and could be used to seek within the Ogg file to a

Everyone, I am building a gateway server with a new : CentOS Linux release 7.3.1611 (Core)??with 3.10.0-514.2.2.el7.x86_64 kernel. Everything was going find, but I was not able to get a particular cronjob to function properly that contained a perl script with Astro::Time as an include file. Astro::Time was installed with the use of the cpan module downloaded from the Centos repositories. The

Hi. I was having trouble getting Greek letters and mathematical symbols in maple under wine, and a search turned up a few messages suggesting others have the same problem.

Dear RGL experts, I haven't been able to add greek letters to my rgl plot3d. I have tried "expression" with no success. Here is the interested bit: > library(rgl) > cb <- cube3d() > plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5) The expression(alpha) appears as "alpha", rather than as a greek symbol. I suspect greek

Hi, Does any one knows how to include greek letters in plot labels and plot titles ? Thanks a lot paul --- [[alternative HTML version deleted]]

Hello all, I can't seem to figure how to use a greek character in expression() in plot() labels without adding a space. So for example below when plotting this out x<-1:10 plot(x,x^2, xlab=expression(Chlorophyll~italic(a)~mu~g~cm^-2)) the axis label read as μ g cm^-2 because I have space there with a tilda. But if I remove the tilda then my units are mug cm^-2. Can anyone recommend a

I would like to add the greek letter mu to replace u in my title shown below. main="R=[0.001uM]:A=[750uM]" i tried using main=expression(R=[0.001~mu~M]:A=[750~mu~M]) but this is not working at the moment. any help is appreciated thanks in advance [[alternative HTML version deleted]]

Dear R-users, I would like to write Greek letters followed by subscripts in a graph (on the X-axis and in a legend).

Hi, Does anyone have any ideas on how to show greek letters on the x and y axes? I have tried > plot(x,y, xlab=expression(delta), ylab=expression(gamma)) but the output on the x-axis is "d" and on the y-axis it is "g". Any help will be very much appreciated. Cheers, Sam.

Hello there, Straight to the point: it seems that CairoPDF from package "Cairo" cannot handle greek letters from expression(). For example, > eta = seq(from=-pi, to=pi, length=100) > f = sin(eta)^2 > pdf(file = "temp_pdf.pdf") > plot(eta, f, type="l", main=expression(f(eta)==sin(eta)^2), xlab=expression(eta), ylab=expression(f(eta))) > dev.off()

Dear All, In the title of a plot, I would like to mix greek letters with numbers, where the numbers are obtained from a particular function to a vector (e.g., max(x)); in each call, the value of this vector can change. Without greek symbols I use something like: title(sub=paste("x1=", deparse(x[1]),"beta = ",deparse(max(x)), "rho = ", deparse(min(x)))) but I'd

I have tried several applications which use Greek letters, such as Maple V R5 and MathCad 2000, and so far I haven't had any luck in getting them to be displayed (nothing is displayed instead). Any ideas? Configuration: XFree86 4.0.2, Debian woody, Linux 2.2.19.

Great setup for the Asterisk@home .06. I have a few questions about the console mode. If you go to the Ctrl Alt F9 area you see asterisk loaded but it's displaying some funny Greek letters. I did the following but it did not help. Eliminating some internationalization errors: In /etc/sysconfig/i18n, the first line reads something like LANG="en_US.UTF-8". Change it to read

Let me summarize the bug reported by Ulf Martin on R-help with the same subject line. The code plot(1:10) text(1, 9, expression(F == bgroup("{", x, ""))) results in greek letters, which is not expected here. That happens if the user tries to set only a left delimeter, the same with: text(2, 8, expression(F == bgroup("{", x, "."))) or

Dear R user community I wanted to use "bgroup" for plotting a math formula with a big "{" on the left, and nothing on the right. i used text( 10, 10, pos=4, cex=1.8, expression(F(x) == bgroup("{", x, "")), ...) on a 40 x 20 plot. surprisingly, bgroup sets "Phi(xi) = { xi" i.e. replaces alphabetic characters with greek letters in the entire

Hi, all. I know that this is probably something that others have asked, but I can't find a reference in either the FAQ or the help pages. I'm trying to find a way to put Greek letters as a label of the plot *with* a value from the data. Previously I've used pasted and the word "rho". * paste("rho=", cor2[i]) will produce a label of
