similar to: R graph strip in Greek Letters

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

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

Hi, Could someone please let me know how to plot greek letters in italic. text(0,14,expression(italic(rho)[italic(f)])) only plots the f in italic and text(37,40,expression(italic(rho))) doesn't plot rho in italic. I have checked demo(plotmath), ?plotmath, FAQ, and the archives 2004-2006 without finding the answer. I'm using R 2.1.1. and Windows XP. Thanks! Tord -- Tord Sn?ll

I have gone over the examples and can't figure this out: rho<-.77 text(x=.05,y=.5,paste(expression(rho),rho)) I was hoping to get this to print a Greek rho with 0.77 beside it. Instead I get: rho 0.77 (i.e. Roman lettering) The help on expression() is quite opaque so I don't understand how it works. Thanks for any help. Bill Simpson

I'm trying something that I thought would be pretty simple, but it's proving quite frustrating... I want to display, for instance, the correlation coefficient "rho" in a graph. I can do something like: text(x, y, paste("rho =", cor)) where cor would be my previously calculated correlation coefficient, and x and y the coordinates. Obviously that displays

In plot() I can get greek symbols into text items without trouble. However, some of the same commands don't work as I would expect with hist(). See the example below. > plot(1:10, 2:11, xlab=expression(paste("scaled", rho))) ---- works as expected, ie. prints the greek rho > hist(c(0,0,0,0,4,5,6,6,6,8), xlab=expression(paste("scaled", rho))) Error: Object

Dear all I solved a problem of customised labels on strips and boxes in bwplot by this construction. > bbb <- bwplot(zavoj ~ typmleti | pu) > bbb$condlevels$pu <- c("Povrchov? ?prava", "Bez PU") > bbb$x.limits <- c("Mleto", "Mleto a s?tov?no", "Nemleto") > bbb but I wonder if some other easy option exist. Let say something

I have tried to print a table of greek alphabet names and symbols without success. I can print one character at a time but can't seem to find a way to automate an entire list of the symbols. Some of the code I have tried is below. I have searched on help, worked the examples in the December 2002 R Help Desk article and plotmath but have not been able to find a way to accomplish the

Hello all R-er, I'm trying to run a resampling method on some data. The current method I have takes 2+ days or a lot of memory . I was wondering if anyone has a better suggestion. Currently I take a matrix and get the correlation matrix from it. This will be called rho.A. Each element in this will be tested against the distribution from the resampled correlation B matrix. Some example

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, I need to add on a plot text containing italic Greek characters using the function mtext (i.e. I cannot use Hershey vectors). The characters are nicely displayed when the file is saved as png but not when saved as eps. See code below as example: #postscript('test.eps') png('test.png') plot(1,1, type = 'n') mtext(side = 3, line = 2,

Hi, I want to write in x axis label "fitted value of lambda" (lambda in greek letter). xlab=expression(lambda) gives the "lambda", I tryed things like xlab=paste ("fitted value of ", expression(lambda)) but I didn't get the greek letter.

I have an instance where I need to include Greek letters on a plot title that is multiple lines. ? I've searched the forums for an approach to do this, but most of the previous posts and replies seem to just address instances of single line examples and problems:, e.g. ? https://stat.ethz.ch/pipermail/r-help/1999-October/005096.html ? I tried implementing those suggestions, e.g.

Dear all, I appreciate suggestions for following problem. I wrote to RStudio: plot(c(1,20),c(1,20), xlab = expression(paste(alfa))) or the same happen when I wrote: plot(c(1,20),c(1,20), xlab = expression(alfa)) what happen is, that description under x label is exactly "alpha", not greek letter alfa (?). Please where should I search problem, or what information to sent to list for

Hi, I am having troubles in putting greek letters and formatted text in a plot m=1.43432 sig=0.124333 text(10.5,0.07,sprintf("<Sigma>=%1.2f±%1.2f",m,sig)) I would like to have the greek letter Sigma followed by the formatted numeric values of m and sig.

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

Hello! My graphs are produced using the "postscript"-option in R (R version 2.10.1 (2009-12-14)). When Greek letters are used on the axis, everything looks fine in the *.ps-file. If included in a LaTeX-file and (on Ubuntu 10.04, fresh install), the Greek letters appear in the DVI- and PS-output, however, if converted with ps2pdf they suddenly disappear. Could anyone suggest a

Hi all, I want to plot a series "x" and I want to put on title "Time evolution with alpha=0.2", e.g., plot(x, main="Time evotion with alpha=0.2",col="orange") Is there any posibility to put the greek letter and avoid written the word? Many thanks in advance. [[alternative HTML version deleted]]
