Hi all, I have a question about expression. In a figure I want to include the term D*obs with the star as as superscript and obs as subscript. I have even just tried to get the star to be superscript. The code I tried was text(Dstar+7,120,expression(paste({}D,^*))), but that doesn't work and I get a syntax error. I can't seem to find anything in the help files that explains it.

Colleagues ---------------------------------- System info: R version rw1022 on NT ESS v. 5.1.18 using emacs ver. 20.4 ---------------------------------- I have some rather unusual units for acoustic volume backscattering integrated over several metres depth and 10 transmits (which happens to = 160 m along transect). I need to express these units in a graph label. My problem

I've tried several different ways to accomplish this, but as yet to no avail. My y-axis for a plot has a rather long label, and thus I have been using "/n" to break it into two lines. However, to make it technically correct for publication, I also need to use superscript in the label. For example: par(oma=c(0,0,2,0),mar=c(5,6,0.25,2),lheight=1) plot(1:10,

I know that this has been revisited over and over, yet I cannot figure out how to solve this case of superscript troubles... I would like the 2 in r2 to be superscript, yet I am pasting text before and after it. I have tried several variations but have not solved this yet, any suggestions? legend (bty =

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

I would like to insert a superscript in a body of text (e.g., a title or axis label), where the superscript is not necessarily at the end of the text. For example, suppose a title read, "This is a Test^1 of the Emergency Broadcast System" where there is a superscript 1 after the word Test. As a starting point for what I'm trying to do, the following shows a superscript:

I am trying to get the following line in a plot margin using mtext: 100% Area = 120.000 km^2 Where I intend that "100% Area =" is text, 120.000 is a number that varies according to different data, and km^2 should be a neat km-with-superscript-2. The expression function fails me, since it apparently cannot coerce an expression when a variable is involved. In the R help file there is

Hello all, I am an R novice and I have a simple question and hope somebody can help me out. I need to place several labels in a plot, this labels are some kind of text and also some objects (which come from some more complicated R calculations). In one of this labels I'd like to place a superscript, however I cannot find a way to place both the expression and the object in the same

Salut, I have been struggling to superscript the 18 before the O without ^ visible and found only help to superscript numbers after the letter.

Dear List, I need to add a subscript and a superscript to some of the ions in the labels on some plots. I have got to here but now I'm stuck: plot(1:10, xlab = expression(paste("nm SO"[4], " ", mu, "eq cm"^{-2}, " yr"^{-1}))) Which gives almost what I require. No matter what I tried, however, I could not get bot a sub script *and* a superscript

Dear List, I'd like to add text to a plot where a text symbol has both a superscript and subscript. For example, the variable S with a superscript 2 and a subscript t. I have been able to accomplish this using either expression( paste(S,atop(scriptstyle(2),scriptstyle(t))) ) or expression( {S[t]}^2 ) but the spacing isn't quite right (or rather what I'd like) using either of

Hi all, I'm having problems finding the correct format for a command. I would like to write some text on a plot. I'm using the following command: text(x,y,"text here", srt=90) I would like the text to read: capacity 10^3 m^3 (with ^ denoting superscript (i.e. each '3' as superscript). I've tried fiddling around with expression(paste(etc.... to no avail. I

I'm attempting to insert variables as expressions into labels for my plots, but I'm running into the issue that characters in my labels aren't allowed in expressions, notably '[' and ']'. An input string of "[^3H]5-CT" needs to be displayed as [3H]5-CT with the 3 as superscript. But brackets aren't particularly liked in expressions. I know I can do

Hi there, How can I superscript the "2" of "r2 =..." in the legend below? legend(210, 110, paste("r2 = ", format(summary(regression)$adj.r.squared,digits=3), sep="")) I usually use "expression(paste(...", but it won't work this time because "format(summary(..." needs to be evaluated.

Hi everyone, I am trying to write a title for a plot which has a superscript like D^2 and a value of a variable stored in that variable..... i am not sure if i am clear so i will try an example: Suppose i want my title to be like: Family: Gaussian; D^2 = 0.45 where i have the value 0.45 stored in variable d2 (which comes from some previous calculations, and depending which actual variables

Hi, How can I get the '2+' into superscript in the following title: '[Ca2+]i onsets' I tried the command below, but it doesn't work.

I am trying to get superscripts on the y-axis. I keeping getting syntax error: This works as advertised: > plot(c(1:10), ylab= expression(paste(x^ theta))) This does not: >plot(c(1:10), ylab= expression(paste(x^ {++}))) Note that I am trying to get ++ as superscript.

I've exceeded the maximum time I am willing to accept for solving simple problems so I thank all in advance for your assistance. I am trying to plot text combined with an object value and a superscript. obv = 5 text = "Population mean =" ss = ^o # degrees Something like this (very naive so you get the idea): expression(text, obv, ss) paste(text, obv) # works ...but of course I

Hi everyone. I'm trying to use small letter phi in a graph produced in R. However, the small letter phi does not look as it should. In fact, it looks like this: http://r.789695.n4.nabble.com/file/n3963311/Untitled.png instead of what is here http://en.wikipedia.org/wiki/Phi Here's the code I use: expression(phi [1]) Anyone has an idea?

Hi, I wonder whether the following is possible with R, and whether anyone has done that and can share his/her code with me. I have a correlation matrix, and I want to create a correlation table that I can copy to Microsoft Word with a superscript above each correlation, indicating significant differences in the same row. That is, when correlations in the same row do not share superscript, it means
