Dear all, I have written a small set of functions for drawing graphical representations of R objects and evaluations of R expressions. It is mainly intended for pedagogical purposes. Here are some samples: http://panini.u-paris10.fr/~sloiseau/sampleGraphics.pdf The idea is to use some graphical conventions in order to make clear the abstract syntax and to explain function, extraction,

Hi, I'm planning to embed R into an application, with the following context: - This application is written in Java (and managed with maven). I plan accessing R using JRI. - This application must be installable on several plateform (linux, mac os, windows). - The R engine must embed library, some of them having native code in C or Fortran. Does this sound reasonable? I would be very

I have posted this message on r-lang, but it is perhaps more appropriate on r-devel: --- Hello, I'm puzzled by a problem with call to diag(), rowSums(), rownames() on objects of class "dgtMatrix", created by sparseMatrix() or spMatrix(). I use Matrix 0.999375-30. The weird thing is that I don't encounter any problem when I use this functions on the R prompt, or

Dear all, I'm facing a strange behavior in the the C code of a R package. This package, "rcqp", is a wrapper on an existing program that I did not write, "CWB". In this package, on a linux (ubuntu and debian) system, the code : printf(%d\n", isupper('A')); outputs : 0 When compiled with the R framework (It behaves correctly when CWB is compiled as a

Dear all, In a new package, I try to check the examples given in the \example section of the Rd files. However, the examples cannot be run if the package is not instructed, during startup time, in the place where some data are to be found ( with system.file("exampleData", "xyz", package="rcqp"). Is there any hook available, or a place where some code might be

Hello, I am currently testing a Vector AR of dim 3 over not a lot of data (135 * 3 observations) . To test the adequation of my vecot ar, I use the Schwarz Bayesian Criterion and the classic modified Portmanteau test on the residuals (it can be found for instance in http://www.iue.it/PUB/ECO2004-8.pdf , page 15) -> the null hypothesis is "the residuals process are a vectorila white

Hello , Is there any function to mesurate the duration of a procedure (like tic and toc in matlab) ? Tic Source("procedure.R") Toc (toc is the duration between the execution of tic and the execution of toc) Thank you nicolas [[alternative HTML version deleted]]

Does anyone know where i can find out how powerful a machine has to be to handle a certain amount of call volume? Eg, 2Ghz is enough processing power to maintain 100 calls at a time. 4Ghz is engouh to process 250 calls etc etc. Thanks Dan -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I want to backup data from my computer located at home to a server located anywhere else and accessible through the Internet at any time. Does anybody know any provider offering a storage service and an rsync server service ? Thank you very much for your answer ... Xav

Hello all, Following a discussion at the end of december [1] I created a package "drawExpression" on R-Forge. It is still in a very early stage! Here is a draft of a PDF "visual reference card" that show the usage of the code: https://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/pkg/visualRefCard/visualRefCard.pdf?rev=3&root=drawexpression&view=log Advices

Dear professors and collegues I need to perform a analysis of dates from a nested experimental design. From "Bioestatical Analysis" of Zar "Bimetry of Sokal" & Rohlf "Design and Analysis of Experiments" of Montgomery I have: Sum (mean(x)_i - mean(x)_T)2 / (a-1) -> var(epsilon) + n sigma2_B + n b (sum alfa_i)2 / (a-1) Sum (mean(x)_ij - mean(x)_i)2 /

Excuse me. I don't understant how to use the function "stack". I'm not sure to know the good syntax. I've got a data witch column names are the time when the mesures was done and an other who indicates the age of the subjetcs. I would like to do a new matrix with patients older than a value and the new matrix will contain in the first column the time of the mesures and in

So in fact : I have a data wich colnames are : "id","VEMS5A","VEMS6A","VEMS7A","VEMS8A","VEMS9A","VEMS10A","VEMS11A","VEMS12A","VEMS13A","VEMS14A","VEMS15A","VEMS16A","VEMS17A","VEMS18A","cohort") With "VEMS5A" is the value when

I made an ANOVA with repeated mesures (aov(Mesure~Distance*Genre*Correct+Error(Sujet/(Distance*Genre*Correct)), data)) and I would like to extract the pvalues. The output is: ----------------------------------------------------------- Error: Sujet Df Sum Sq Mean Sq F value Pr(>F) Residuals 21 97.082 4.623 Error: Sujet:Distance Df Sum Sq Mean Sq F value Pr(>F) Distance

I have a .txt file obtained by saving a data frame in which the first four columns are factors (but represented as 1,2,3 etc). The first four lines are "Pig" "Evit" "Cu" "Litter" "Start" "Weight" "Feed" "Time" "4601" "1" "1" "1" 26.5 26.5 NA 1 "4601" "1"

hi everybody, I'm a student, and I'm new using R! I'm looking for statistical help hoping somebody can answer me! This is my problem: I have 2 temporal series. The firstone is a series of mesured data (height of monitorated points), the second is a series of temperature (in Celsius degree). Using Matlab I have built the two graphs (Measured Data - Time & Temperature -

I have to study censured datas concernig the occurence of infection at the point of insertion of catheter in patients with renal disease. Catheter may be removed for ather reasons than infection, in this case, the observation is censored. Each has exactly 2 observations. The question are the pronostic factors of infection (the other variables are; age, sex, type of renal disease...). Could you

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
