Hi, I have to R fairly recently from Matlab, where I have been used to organising my own custom functions into directories which are adding to the Matlab search path. This enables me to call them as I would one of Matlab's built-in functions. I have not found a way of doing the same thing in R. I have resorted to using source() on symlinks located in the current directory. Not very

Hi everyone, I am trying to cross-compile a package I wrote using the Yan and Rossini tutorial "Building Microsoft Windows versions of R and R packages using Intel Linux". I have got reasonably far with this but when doing the linking using the line: i586-mingw32-g++ -shared -s -o mylibrary.dll mylibrary.def mylibrary.o mylibrary_res.o

Hello, For no apparent reason Rsync is uploading the whole file even though the the remote file is identical to the local file.

Good morning everybody, I am integrating some modifications in the LLVM parser (specifically in the LLParser.cpp file), by adding calls to functions that I have defined elsewhere in a file called MyLibrary.cpp. How can I integrate such library in the overall tree? I would like to have a MyLibrary folder under lib/ so that I can access it from different parts of the code. Where should I put

Hello All I am trying to get the JRI examples from rJava to work on Windows XP and failing. (And as a more general and connected question is there any review/summary of front-end software for R?) I have installed rJava from the Windows binary supplied. I compile and run the example supplied (rtest.java) and get the results below. I do not think the notes about a deprecated API are a problem. But

(Before starting: I'm a total R noob so please bear with me in case of any error or faux pas). Hi, For a small project, I'm writing a few simple R functions and calling them from python (using RPy). I'm sharing the code with a couple of friends, using a subversion server. Now, I want something like a package, to be able to share functions between ourselves. Having read a few package

If I use the Ineq library and the Gini function in this way: >Gini(c(100,0,0,0)) I obtain the result 0.75 instead of 1 (that is the perfect inequality). I think Gini's formula in Ineq is based on a formula as reported here: http://mathworld.wolfram.com/GiniCoefficient.html but in the case of perfect inequality: x_1=.......=x_n-1 =0 x_n>0 these formula are equal to 1 - 1/n, not to

Hi, I want to set up a dynamic link between a library e.g. myLibrary.a and a C++ file myProgram.cc to use in R. Is this possible? If so how does one go about doing it? Any help will be greatly appreciated. Cheers, Sam.

Dear Sir/Madam, I got some problem about using R. I am a student, and need to use R a lot. But sometimes when I am working in computer lab, we can not install some particular pacakges by ourselves because of the previliges. Can the folder of Librabry of R, move to, for instance the personal folder, my documents... then we can install any specified package? Best regards,

Hi, all How to format and join strings ? For example, like following short python examples. ********* name1 = 'sample-plot' filename = '%s.png' % name1 inputdir = '/path/to/dir' os.path.join(inputdir, filename) ********** Best, Hyunchul Kim [[alternative HTML version deleted]]

> Dear R-users! > > I am using R 1.0.0 and Windows NT 4.0 > In the past I have used several different working directories for different projects, and during many of these projects I have written some functions for particular purposes. Now I thought I would be nice to have all these "personal" functions collected in one place, and to make them available in R no matter which

Well, after some investigation I have a few more clues as to what is going on. I have a module which contains a call to an external native function. This native function lives in a static library, and there is an external declaration for it in the module. I find that I can run "llvm-ld -disable-opts -native -l mylibrary test.bc" and it works fine. That is, llvm-ld is able to

Hi, How does R automatically load functions so that they are available from the workspace? Is it anything like Matlab - you just specify a directory path and it finds it? The reason I ask is because I found a really nice script that I would like to use on a regular basis, and it would be nice not to have to 'copy and paste' it into R on every startup:

Hi all, This information must be out there, but I can't seem to find it. What I want to do is to store functions I've created (as .R files or in whatever form) and then load them when I need them (or on startup) so that I can access without cluttering my program with the function code. This seems like it should be easy, but.... Thanks! Jeff

Sounds like LLVM thinks the calling conventions or declarations are mismatched.

Hello, What options are available for me to debug my R scripts? For example I normally do something like >source("myfunctions.R") >function1("height", "weight") myfunctions.R is a large R source file that contains many functions. function1 is the "main" function in myfunctions.R. It calls many other user-written functions that are also in

R-help, Sometimes I define functions I wish to have in any R session. The obvious thing to do is copy-paste the code The thing is that sometimes I don't know where I have the function code. My question is if somehow I could define a function and "introduce" it (let's say 'base' package ) so that could be used anytime I run a different R project. Thank you in advance

I am trying to build a package using windows xp. Here is the error I am getting: R CMD build myfunctions * checking for file 'myfunctions/DESCRIPTION' ...

Hi everybody, I started to receive a weird message in R that I have never seen before...also I haven't found anything on google or on this forum about it. Whenever I use the command source(...) to point to one of my scripts, I get the following message: Error in source("myfunctions.R") : myfunctions.R:884:9: unexpected symbol 883: 884: cond ^ I am
