Hi I am using mathematical anotation to make the labels in a barplot in italics. as an example (adapted from http://finzi.psych.upenn.edu/R/Rhelp02a/archive/129808.html): tt <- c("italic(First~~set)", "italic(Second~~set)", "italic(third~~set") barplot(1:3, names.arg=parse(text=tt)) But I would like to have it with "set" in a second column, like tt

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. Any suggestions? Thanks. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing

I discovered recently that the phrase "Oja median" produces no hits in Jonathan Baron's very valuable R search engine. I found this surprising since I've long regarded this idea as one of the more interesting notions in the multivariate robustness literature. To begin to remedy this oversight I wrote a bivariate version and then decided that writing a general p-variate version

Hi.. I managed to use expression() for superscripting and subscripting values in my axis labels. However, I notice that the font and style that I had passed through par() are ignored. I used : par(font.lab=2, font=2, family="sans") but when I employ expression() for my xlab, the styling given above is completely ignored. I would greatly appreciate it if someone knew of a method of

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

Paul Murrell and I are making some progress with making mathematical expressions available in graphs. The idea is to use R expressions to represent the mathematical expressions. So far we have (or will soon have): R LaTeX x^i x^i x[i] x_i alpha \alpha Alpha \Alpha hat(x) \hat{x} \widehat{x} bar(x) \bar{x} \overline{x} x+y x+y x-y x-y x/y x/y (x) (x) {x} {x} frac(x,y)

Dear R-users, I'm trying to add a title on a plot with both mathematical notation and values substitution. I read the documentation and search the mailing list but I was not able to solve my problem. Actually, there is a message by Uwe Ligges on June 2003 which addresses a question very close to mine, but the code provided doesn't work. The code is the following: # I add this to let you

Hi all, I have a problem using rdirichlet{gtools}. For Dir( a1, a2, ..., a_n), its mode can be found at $( a_i -1)/ ( \sum_{i}a_i - n)$; The means are $a_i / (\sum_{i} a_i ) $; I tried to study the above properties using rdirichlet from gtools. The code are: ############## library(gtools) alpha = c(1,3,9) #totoal=13 mean.expect = c(1/13, 3/13, 9/13) mode.expect = c(0, 2/10, 8/10) #

Spencer Thanks for your thoughts on this. I did a bit of work and did end up with a method (more a trick), but it did work. I am certain there are better ways to do this, but here is how I resolved the issue. The integral I need to evaluate is \begin{equation} \frac{\int_c^{\infty} p(x|\theta)f(\theta)d\theta} {\int_{-\infty}^{\infty} p(x|\theta)f(\theta)d\theta} \end{equation} Where

Hi, I am using R 2.9.0. It seems the documentation for the calculation of Canberra distance using stats::dist is ambiguous. Does anyone have the original definition given in the Lance & Williams paper from Aust. Comput. J. 1, 15-20, 1967? When there are zeros at certain position in both vectors, they are not omitted as documented in the function (see below). Instead, Canberra distance is

In Version 0.64.1 (May 8, 1999), Solaris 2.5.1, expression(theta^{-}) and expression(theta^{+}) (and the equivalent subscripts) give syntax errors. (Superscript or subscripts of numbers, letters, or "+1" or "-1" all work.) Anyone have a workaround or a patch? Or should I just use psfrag as god intended? Ben Benjamin Bolker Dep't

Hello, I am using constrOptim to maximize a likelihood function (the values of my parameter vector must be between zero and one and must sum up to <=1). I am getting the error 'initial value in 'vmmin' is not finite'. I've tracked it down to a problem in the function 'R' defined within the constrOptim function. It is performing a check on my values, and its not

Hi, I'm having a problem using LME and hopefully I can get some help. Here is what I'm doing: I have a model like this: yi = alpha + theta * xi + beta * zi + error, errors are normally distributed mean 0, var sigma^2 xi and zi are generated from normal distributions within a specified range. True values of alpha, theta, beta and sigma^2 are chosen with a specific mean and variane

R-Listers: I am doing a quasi-maximum likelihood estimation and I get a "subscript out of bound" error message, Typically I would think this means that a subscript used in the function is literally out of bounds however I don't think this is the case. All I change in the code is a constant, that is hard-wired in (not data dependent and not parameter dependent), furthermore,

Dear R users, I recently developed a plotting function in R and introduced it to my coworkers. The function is designed to make plotting easier and more efficient, which will in turn be more cost-effective for the company. The reviews for the function have been positive thus far, except for one issue -- addition of superscripts to the title. We need superscipts in the titles sometimes to

Why doesn't R have one, like "." in Perl or juxtaposition in awk? It does not seem impossible to introduce one, if that would be reasonable. It would seem to involve adding a table entry to main/names.c for the binary operator and a corresponding internal function, say do_dot(). This cannot be simply do_paste(), since the implied separator is "". So, do_dot() might be

Hi Folks, I am dealing with data which have been presented as at each x_i, mean m_i of the y-values at x_i, sd s_i of the y-values at x_i number n_i of the y-values at x_i and I want to linearly regress y on x. There does not seem to be an option to 'lm' which can deal with such data directly, though the regression problem could be algebraically
