similar to: greek letters, text, and values in labels

Recent questions about using plotmath have renewed my interest in this question I want to have expressions take values of variables from the environment. I am able to use expressions, and I am able to use paste to put text and values of variables into plots. But the two things just won't work together. Here is some example code that shows what I mean. plot(NA,xlim=c(0,100),ylim=c(0,100))

Dear all, I have a vector of expressions and would like to "paste" some string to it before using it in a plot: vars <- vector("expression", 2) vars[1] <- expression(alpha) vars[2] <- expression(beta) plot(0, 0, main=substitute(bold("Foo" ~~ VAR), list(VAR=vars[2]) )) Although I tried hard, I just can't figure out how to solve this. The title should be

Hello This is a problem I encountered repeatedly and I found no answer that made me really happy. I hope it is not too trivial. I would like to give the concentration of a substance in a plot title: 5 ug/ml substance the '5' would be a variable and the ug should be micrograms (with greek letter mu). It is the mu that causes the problems for me. I failed using various combinations of

Dear R Helpers: I am trying to annotate a plot. The following code snippet works, but it is kind of a kludge since it adds the partial derivative symbols after creating the plotmath frac(). Is there a more elegant way to write a partial derivative? dev.off() plot(NA, xlim=c(-3,3), ylim=c(0,1.6), xlab="", ylab="", tck=-0.015) text(1.6, 1, expression(paste("slope =

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'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, 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

Hello, I have written a function that demonstrates the CLT by generating samples following the exponential distribution, calculating the means, plotting the histogram, and drawing the limiting normal curve as an overlay. I have the title of each histogram state the sample size and rate (1/theta) for the exponential (the output is actually 4 histograms), but I can't get the greek letter theta

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:

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 ran into a problem with titles on graphs. I wanted a graph with multiple subplots, with each having a title that involved both a Greek letter and an identifier for each graph. Below is a simplified version of code to do this. The graph appears fine, with the first graph having "i=1" in the title, and the second graph having "i=2" in the title. However, when I resize 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

Hello, I am plotting a 3D function using persp and I would like to use greek symbols in the axes labels. I have found examples like this one on the web: plot(0,0,xlab=expression(kappa[lambda]),ylab=substitute(paste(phi,"=",true,sigma),list(true=5))) this works well with plot but not with persp: with the command persp(M,theta = -20,phi =

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

Full_Name: Ramin Nakisa Version: 1.1.0 OS: i386 linux Submission from: (NULL) (192.127.94.7) Labels created with expression seem to disappear, e.g. the x axis label in x <- -6:16 contour(outer(x, x), method = "edge", vfont = c("sans serif", "plain"), xlab=expression(theta[0]), ylab=expression(theta[1])) and all three labels in x <- -6:16 persp(outer(x, x),

I have tried the following code to plot and save many box plots in files. The code works by itself, but does not run in a loop. The error indicates that there is no device. The error is printed below the code. Code: for(i in 1:len) { A = as.numeric(delta[Delta[i,1]]) B = as.numeric(delta[Delta[i,2]]) C = as.numeric(delta[Delta[i,3]]) D = as.numeric(delta[Delta[i,4]]) data

This problem has bugged me for several years now, and our own IT staff has tried a few things, but then never cared enough to persist fixing it. It *is* a bug in evince, the standard pdf viewer on Fedora and IIUC also quite few other Linux distributions, and *not* a bug in R; hence I am asking for help/hints here. A very simple example:

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

I can't believe I'm having such a hard time with this and I haven't been able to find out how to solve this... lab <- expression( paste( hat(v), as.character(round(y.hat,2)), ",", hat(sigma)^2, as.character(sigma.hat)) ) text( x=pt$x+2, y=pt$y,labels=lab ) ## the text should be \hat{y} = <value of y.hat>, \hat{\sigma}^2 == <value of sigma.hat> and R

Dear People, I need to make a label which both contains math notation as well as substitutes a value for an object. In the following label, len and theta are one dim variables, and I am substituting their values appropriately. This label looks fine except that I want the greek symbol for theta to appear instead of the word `theta'. How can I do so most easily? I don't understand the
