similar to: Variables and greek letters in a plot title

Hello, I want to have a title that will look something like: "Results for \theta=2.1", given that I have a variable theta=2.1, and \theta should show on the screen like the greek letter. I've tried a lot of things: theta <- 2.1 plot(1:10, main=expression(paste("Results for", theta, "=", eval(theta)))) or using bquote plot(1:10, main=paste("Results for

Hi - I've been using the option main=bquote(paste(mu==.(mu),", ",lambda==.(lambda),", ",truncation==.(truncation),", ",N[T]==.(n))) to produce a title when using the "plot" command - a title which includes variable names (two Greek) along with their values. The above option, however, does not work within the "boxplot" command. Any

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

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

I had such good luck with my previous question to r-help, (a few minutes ago) that I thought I would try again with the following query: > Suppose I have > > xNm <- "gamma" > > I would like to be able to do > > plot(1:10,xlab = <something involving xNm">) > > and get the x axis label to be the Greek letter gamma > (rather than the

I'd like to annotate a lattice plot, e.g. xyplot, with text containing both Greek letters and variable values. In the base graphics plot command this can be accomplished with e.g. main = substitute(paste(lambda,"=",var),list(var=var)), where var is a variable that contains the value. When I try to do this in xyplot, I get the error message "object 'lambda' not

Dear r-help list, I am trying to combine a greek letter lambda with the contents of a variable v in the title of a plot. However, it seems that having v inside the expression() function causes it not to be evaluated, on the other hand having expression(lambda) inside something else like paste causes it to be evaluated to a string. Here is an example of what I want to do:

Following on from my previous mail! plot(1:10,1:10) mtext("title", side=3, adj=0, font=3, cex=1.5) This works as expected and puts the font in italics. tag <- "A)" suffix <- "genea::" plot(1:10,1:10) mtext(bquote(.(tag) ~ Delta * .(suffix)), side=3, adj=0, font=3, cex=1.5) Here, the font isn't in italics, it's normal. I presume this is some

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

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

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, 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. Thanks in advance for any hint. Antonio Olinto ------------------------------------------------- WebMail Bignet - O seu

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

Hi all, I have one question on xyplot() function.
