Dear list, I read in ?plotmath that I can use bgroup to draw scalable delimiters such as [ ] and ( ). The same technique fails with < > however, and I cannot find a workaround, grid.text(expression(bgroup("<",atop(x,y),">"))) Error in bgroup("<", atop(x, y), ">") : invalid group delimiter Regards, baptiste sessionInfo() R version

Hi, I'm trying to understand whether the use of substitute() is appropriate/documented for plotmath annotation. The following two calls give the same results: > plot(1:10, main = expression(alpha == 1)) > do.call(plot, list(1:10, main = expression(alpha == 1))) But not these two: > plot(1:10, main = substitute(alpha == a, list(a = 2))) > do.call(plot, list(1:10, main =

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.

Hello, I am trying to get a time derivative on a plot title. I prefer to have it in the form \dot{s_i}, but \partial s_i/\partial t would be O.K. In the graphics demo I cannot find either a dot or a partial equivalent.

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

Hi, Although I understand how to use expression and paste to add superscripts and symbols to my graphs, I have a problem with adding superscripts to an existing string. For example, I read in the following from a separate file: 25Mg(p,g) I want to convert that to superscripts etc. (in LaTex format): $^{25}$Mg(p,$\gamma$) This needs to then be put into a graph title. Any ideas? I know that I

Hi Thanks for your input on this I?aki and Nicolas. I am starting testing an R fix for this problem today. As suggested, the plan is to allow the R user to specify a font family other than "symbol" for plotmath output (or, more generally, in R parlance, for 'font=5' or 'fontface=5') on a Cairo-based graphics device.

Hey, Does anyone know of an equivalent to the LaTeX \perp (perpendicular) symbol for adding to R plots? Parallel is easy enough ("||"), but I haven't been able to find a way of adding perpendicular. The plotmath documentation doesn't mention how to do it, so I'm inclined to think that it doesn't exist - but surely there must be some way of achieving the desired result,

I would like to know if a MetaPost device is available or in the plans. A search MetaPost in the documents and list archives did not turn up anything. [I would prefer to use MetaPost when the graphics is to be included in a document that I want in both hard-copy and in pdf formats.] If not, how easy/hard is it to add a new device to R? I caouln't see anything about adding devices in the

Hi The R branch ... https://svn.r-project.org/R/branches/R-symfam/ ... is now set up so that it works "out of the box" on Fedora by setting the default to be 'symbolfamily=cairoSymbolFont(family, usePUA=FALSE)' when grSoftVersion()["pango"] is greater than "1.44". This means that on Fedora 31 (at least on the Docker container I am testing on)

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))

In plotmath expressions, R's degree symbol, e.g. shown by plot(1, main = parse(text = "1*degree*C")) has sunk to halfway the text line, instead of touching its top. In older R versions this looked much better. -- Edzer Pebesma Institute for Geoinformatics Heisenbergstrasse 2, 48151 Muenster, Germany Phone: +49 251 8333081

Is there anything R can do that Splus can't? I know about the differences in the language but what about statistical functionality. Are there models you can build or graphs you can plot in R that you can't in Splus? My impression is that in this respect R is strictly a subset. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Paul et al, I will try to do this tonight or tomorrow, though it will not be built with th system tools because I have yet to get that tto work locally (spent a good chunk of this morning trying). I will send a separate messaage regarding those difficulties as well so that we can at least confirm that they are due to a malconfiguration on my part. Best, ~G On Tue, Apr 7, 2020 at 7:25 PM Paul
