Hello, I am beginning with R and I would like to test a non linear model. But I do not find exactly wath I am looking for in nls packages (or I do not know where to search). I would like to try a model like this : y=b * x exp(n)/(a exp(n) + x exp (n)) Where a = a0 + a1z b= b0 + b1z x and z are variables y the variable that I am trying to modelise a0, a1, b0 and b1 are parameters to determine. I

Hello, I would like to know if (as the usa map with Splus), it is possible with R to plot the french map and to add points (representing towns for instance) on the figure in the appropriate (x,y) system. Thank you. Nathalie Peyrard

Hi, I'm trying to use the "usr" argument but I see no effect of this option on my plots. For example: > par(usr=c(0,4,0,4)) > plot(1,1) This plots one point fine, but the coordinates of the plotting region are not those that I specified using par()... I can check this with > par("usr") [1] 0.568 1.432 0.568 1.432 What can I change in order to have this

Dear R-users, Is there an easy way to avoid points one upon another when ploting rows and columns of 'dudi' objects ? Maybe there is a function in ade4 or in an other package, or maybe someone has his or her own function to do this (for example to automatically modify a little the coordinates of these points to get a readable plot ?). Thanks in advance. Best regards, Jacques VESLOT

Hi, I'd like to know if it is possible to use Hershey vector fonts to create very primitive musical notation. If I can hang some whole notes on these lines X11() plot(0,0, xlim=c(0,10), ylim=c(0,10)) # Staves: for (i in c(seq(from=2,to=2.8,by=0.2),seq(from=4,to=4.8,by=0.2))) { abline(h=i) } it is enough.

Hi all, suppose there is a vector y with rownames: > y cond1 cond2 cond3 cond4 78.952 87.308 86.490 74.040 how can I easily plot this vector using the rownames? plot(y) gives me a plot with a x-axis from 1 to 4 in 0.5 steps, also plot(rownames(y), y) and plot(y ~ rownames(y) don't work. I know I can build a x-axis with axis(1, ...), but in this case I need a character string like

hello, I work since a few time on R and i wanted to know how to obtain the Wald chi square value when you make a binary logistic regression. In fact, i have the z value and the signification but is there a script to see what is the value of Wald chi square. You can see my model below, Best regards, S??verine Erhel [Previously saved workspace restored] > m3 = glm(reponse2 ~ form +

Hi, I want to make a plot with abline where the area below or above the curve is shaded. I can't find any documentation on that. Can anybody help me with that? thanks, Juffi

Has anyone got vim to have syntax highlighting with R function codes? I know there's something similar that works with emacs (ESS or something like that), but I was wondering if anyone knew an equivalent that worked with vim.

Hello I am working on radio tracking data, with a short programme someone gave me and ... which should, supposedly, work ... In this programme, there is the function : getareahr(kern, levels = 95). But i cannot find any 'getareahr' in R ... could anyone help me? thanks! Agn??s

Hi all I'm using Sweave and find it a treat. But one question: I use Sweave to create my pictures which are automatically included into LaTeX. For example, in the file test.Snw, I may have: % LaTeX stuff \begin{figure} <<fig=true,width=5,height=5>>= x1 <- seq(1,5, length=10) x2 <- sin(x1) plot(x1,x2) @ \caption{Plot} \end{figure} % More LaTeX This produces the LaTeX

Hi I'd like to use R in epidemiology and disease surveillance. In EpiInfo you can have a script (.pgm) which calls a predefined report (.rpt), where a table is calculated and values picked from that table and placed where the author of the report wants them, with text around those values. (Please see example below.) I've looked at manuals, faq, mail-search and google. The closest is an

Dear R users, I have just upgraded R from 2.11 to 2.12 on Ubuntu 9.04 (see more informations at the end) from the cran apt-get repository. One of the new things concerning the install.packages() function is stated here : install.packages() and remove.packages() with lib unspecified and multiple libraries in .libPaths() inform the user of the library location used with a message

Greetings, I'm posting this OT query here because of out very international membership! In the French sentence "Les taux de tirage sont calcul??s de mani??re ?? ce que la dispersion soit inf??rieure ?? 5 % dans chaque strate." it would seem intended that the "dispersion" is to be calculated in a specific way (unstated) -- otherwise, how to ensure that it shall be

Hi, I have searched the lists but still can not solve the problem. I am using a windows machine. After I sweave some Rnw file, I got a tex file. However, the tex file can not be compiled. I know the problem is in the line \usepackage{C:/PROGRA~1/R/R-25~1.1/share/texmf/Sweave} and I need to modify this line to \usepackage{Sweave}. I hope there can be some automatic way to do this instead of
