similar to: Calling R from Java

Madam, I've read your answer : /////////////////////////////////////// Here are other alternatives that are easy to implement and that you should consider depending on what you want to do: 1- one is to use R in batch mode ie you create a file in your java code with all the R commands and send it to R (via Process pc=Runtime.getRuntime().exec(Rcall); )and then R creates an

Hello everyone, How can I specify in tcltk file browser the initial directory to "MyComputer" in Windows where Drives and Partition are accessible? And just a little question if anyone knows, is there a way to use the function choose.files under windows to select a directory? Thanks a lot for your help. Laetitia.

Madame, I've read your answer for using R from Java, you've sais: one is to use R in batch mode ie you create a file in your java code with all the R commands and send it to R (via Process pc=Runtime.getRuntime().exec(Rcall); )and then R creates an outputfile with all the results. My question is how to do a process in Java and do I need to change the path of Java or R to let

Hi, I have R installed under a Mandrake linux system and I don't have shell utilities any more under my R console such as completion when writing a file path, back and forth in the history, bindkeys... Moreover when I quit R by saving, no .Rhistory file is created while the .Rdata is. I don't get how this work, I thought it was based on the user unix shell but it does not seem. Any

Hi everyone, I want to write a function that modify directly variables passed as parameters (the equivalent in C language of *ptr/&ptr) so that I don't have to return a list and to reaffect all my variables. Is it possible to do so in R? Thanks a lot. Laetitia Marisa.

Hello, When I launch a script under windows it does not display sequentially my cat calls or maybe the console is not refreshed at every line of my script. For instance with that code cat("\n\n================== IMPORT DATA FROM FILE ===================\n\n") fileschosen <- choose.files(caption="Select gpr files", filters = matrix(c("genepix

Hello, Is there a simple and fast function that returns a vector of the number of replications for each object of a vector ? For example : I have a vector of IDs : ids <- c( "ID1", "ID2", "ID2", "ID3", "ID3","ID3", "ID5") I want the function returns the following vector where each term is the number of replicates for the

Hi, I'm trying to install RSPython v0.5-4 on a debian machine (woody, testing) but am having the following problem. $R CMD INSTALL -c --library=/usr/lib/R/library RSPython_0.5-4.tar.gz 2>err But then... $python >> import RS Error in .PythonInit() : Error in Python call: values Error in library("RSPython") : .First.lib failed for 'RSPython' Traceback (most recent

In the previous versions of R (2.6.1), when a vector of NA was given to the functions 'sd' or 'var' with parameter na.rm = TRUE, it used to return NA. Now (2.7.1) it returns an ERROR : Example in 2.6.1: > sd(c(NA, NA, NA, NA), na.rm = TRUE) [1] NA Example in 2.7.1: > sd(c(NA, NA, NA, NA), na.rm = TRUE) Error in var(x, na.rm = na.rm) : paires d'éléments

I don't rcall seeing this one reported before: plot(...,axes=F) removes not only the axes, but also the plot boundary. The 'bty' parameter loses its effect completely. getting it back seems to require fiddling with par("usr") and rect() or lines() (Linux, Alpha-3) -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200

Hello World, I have a function that makes pairwise comparisons between two strings. I would like to apply this function to my data (which consists of columns with different strings) in the way that it compares the first with the second entry, and then the third with the fourth, and then the fifth with the sixth, and so on down each column... So (2x-1) and (2x) would be the different entries to be

But you can easily fall back to R from within Julia; see http://juliastats.github.io/RCall.jl/latest/ On Aug 5, 2016 1:27 PM, "Hadley Wickham" <h.wickham at gmail.com> wrote: > No. > > Hadley > > On Fri, Aug 5, 2016 at 11:12 AM, Kenny Bell <kmbell56 at gmail.com> wrote: > > Is it conceivable that Julia could be ported to use R syntax in a way > that

Dear R users, I am trying to fit a glm with a distribution free family, link = log and variance = constant*mu. I guess I have to use the quasi family but the choices of variance are restricted to constant or mu or mu^2..., I don't know the way to choose the variance that I need, i.e. constant*mu. If you have any ideas or advice, please tell me. Thanks, Laetitia Mestdagh Laetitia Mestdagh

Hi! Does anybody know a string function that would calculate how many characters two strings share? I.e. ("Hello World","Hello Peter") would be 7. Thanks. Laetitia

Help! Being a bit of a novice, please bear with me if this is a stupid question! I am trying to fit a saturated model to some count data that I have: model<-glm(COUNT~SP*LOC*COL*TIME*TREAT,poisson) but R keeps on crashing and coming up with (occasionally before crashing) an error that states: Algorithm did not converge in: (if(is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,

Thanks for your help Duncan. Your last comment helped me to figure out what FreeBSD was doing differently than Linux/Solaris. This fix worked on a machine with Python 2.1, R 1.3.1 and FreeBSD 4.1. Here are the details: The pthreads fix: I added '-lc_r' to the PKG_LIBS definition in src/Makevars.in. The FreeBSD 'man pthread' page suggests that adding -pthread to the gcc statement
