There's something (probably a lot) missing in my understanding of plotmath. The LaTeX code for what I'm trying to produce is \log(-\log(\hat R)) My (probably hopeless) attempt at it uses nested group()s: expression(plain(log) * group("(", -plain(log)*group("(", \hat(R), ")"), ")")) Can anyone do it right for me, please? Thanks, Ted. Dr E.A.

Folks: delta <- 1:5 I would like to put 5 separate lines of text of the form "10 %+-% delta[i]" into a lattice key legend, where ""%+-%" is the plotmath plus/minus symbol and delta[i] is the ith value of delta. The construct: lapply(delta,function(d)bquote(10%+-%.(d))) appears to produce a list of expressions of the correct form, and, indeed, if I assign the above

Full_Name: Wolfgang Huber Version: R-2.0.1 OS: HP-UX B.11.23 ia64 Submission from: (NULL) (81.104.215.6) Hi, I hope I am not missing something basic... I am using a somewhat exotic compiler and OS, but if I understand what I am seeing the problem is more general: In src/main/plotmath.c, the following function is defined /* Thickness of rules */ static double RuleThickness() { return

This is a followup to a recent post on using atop() to obtain multiline expressions. My reading of the plotmath docs makes it clear that issuing (in base graphics) the specification par(cex = 2) doubles symbols and regular text in subsequent plotmath expressions. However, it is unclear to me what specifying cex _within_ the annotation function using plotmath should do, and the following seems

I'm using R-2.6.2 on Fedora Linux 9. I've been experimenting with plotmath. I wish it were easier to combine expressions in plotmath with values from the R program itself. There are two parameters in the following example, the mean "mymean" and standard deviation "mystd". I am able to use bquote to write elements into the graph title like mu = mymean and R will

Full_Name: Murray H Smith Version: 1.7.1 OS: Windows2000 Submission from: (NULL) (202.36.29.1) This alleged bug is Windows specific and occurs when using Windows metafile plots. The problem does not occur in a Linux version. It does not occur in the pt rintout when a graphic is saved to a postscript file under Windows. The problem came to light when using plotmath to label a plot with

sorry, I forgot my sessionInfo: please see below. -------- Original Message -------- Subject: puzzled with plotmath Date: Thu, 20 Jan 2011 12:48:18 +0100 From: Claudia Beleites <cbeleites at units.it> To: R Help <r-help at r-project.org> Dear all, I'm puzzled with matrix indices in plotmath. I'm plotting matrix elements: Z [i, i], and I'd like to put that as label.

I am interested to use plotmath functions within a panel function but am having some problems getting the code right. Within each panel I am plotting the data, fitting a regression line, and would like to print the regression equation. Here is a trivial example of what I'd like to do: # generate simple data tmp.df <- data.frame(id = rep(1:4, each=4), time = rep(1:4, 4), das =

Occasionally I have had plotmath refuse to draw x-axis labels. This has happened when the label, created using expression(paste( ) ) as below, could be drawn easily in the available space. I have not reproduced that, but the following example with a clearly overly long label results in no xlab at all. I hoped that at least a truncated label would be plotted. This is probably related to my

I hope to use the plotmath facility to print titles that mix math and values of R variables. The help for "plotmath" has an example, which after repeated reading, I find baffling. Likewise, I have read the help file for "substitute" (wqhich seems to be needed) without ever understanding what it does, other than being used in some magic incantations. I would like to do

Hello, I have a problem with the plotmath facility and haven't found any solution in the FAQ and Online-Help. I am trying to incorporate the value of a variable in an expression for an axis with plotmath. Considering having > gamma <- 10 I'd like to have a plot with > plot( .... , xlab=expression(gamma==10)) but depending on the true value of the variable. How can I

Dear all, I just stumbled over the fact that subsetting by square bracket will only output the first given index. I guess the rest is thrown away by the CADDR in RenderSub (plotmath.c l. 1399). Maybe changing this could be considered as "low-priority desired" (would be nice if the output works for ? However, I suggest to announce the fact that only the first parameter is printed in

ComRades, How do you put a superscript on a scalable delimiter? I want to put 'b' as the power of the expression in the following plot: t <- 1:25 K <- 0.2 y <- ((1-exp(-K*t))/(1-exp(-K*t)*exp(K)))^3 plot(t,y,"l",main="K=0.2, b=3") text(15,5,expression(bgroup("(",frac(1-e^-Kt,1-e^-Kt*e^K),")"))) Plotmath examples in demo(plotmath) do not

Dear R-helpers, I have been using \n in my plot titles to split long titles into two lines. I recently tried combining \n and plotmath which still gives me two lines for the title but also a weird blank spacing. A simple example is as follows: plot(1:10, main=expression(paste("Exposure\nTemp (", degree*F, ")"))) Is there something I'm missing to close the spacing.

Is there a hook that allows a graphics device to apply transformations to plotmath expressions *before* they are rendered? If there isn't one yet, would it be feasible to add one? The motivation for this hook is graphic devices that feed into something that already has support for math layout, such as the tikzDevice package (which has TeX downstream). Given text(x, y,

I've been testing plotmath. But I'm getting some funny output one one computer. The problem is that characters are 'jumbled' and overstrike when symbols are introduced. Sample code: mu <- 440.0 sigma <- 12.5 myx <- seq( mu - 4*sigma, mu+ 4*sigma, length.out=500) myDensity <- dnorm(myx,mean=mu,sd=sigma) # Here's one way to retrieve the values of mu and sigma and

R listers: I have been foiled by plotmath! (in R 2.01,Windows 2000) The task: Plot a normal density and label the ticks as mu - 3 sigma, mu - 2 sigma, ...., mu + 3 sigma, where the mu's and sigmas appear as Greek symbols, of course. The following code does this: x<-seq(-3,to=3,by=.01) y<-dnorm(x) plot(x,y,type='h',col='lightblue',axes=FALSE)

I'm trying to annotate some graphics using plotmath and finding out that the code I'm using isn't bolding the greek letters - it bolds the rest (once I adjusted the numerics to characters), it's just failing on the greek characters. Any suggestions welcomed. Jim Price. Cardiome Pharma Corp. Test code: plot(1:5, type = 'n') # The not bold version text(2, 2:4, cex =

Is it possible to use the '\ell' (i.e. the log likelihood) in plots? I've been browsing the plotmath documentation unsucesfully.
