Dear all My dataframe has > 80,000 variables which I can not everytime load into R using *.txt files (read.table option), cost me time and sometime computer decomes not responsive. So I need a way to save my dataframe in my workdirectory as such. Execuse me if the problem is too simple. I tried the following, I do not know what is wrong with it: Example data: x <- 1:10 y <- 21:30 z

Hi All, After successfully installing the AIX Binaries (Thanks Bill), and manageing to join as a ADS Domain Member I have a couple of peculiarities of which I need to get to the bottom. Problem A When connecting to a share, I can connect OK , and get authenticated OK, I can create files in the share and open files in the share, but cannot list files in the share or delete files I have created.

All, I've encountered the same problem as others who have posted under the same subject. I've had R-1.8.1 installed and running since it was released. Yesterday morning when I tried to start Rgui.exe I got the subject error message. Since I live at the whim of the network administrators I can only assume it was a recent MS critical update. I tried installing R-1.9.0 but no joy. I

Hi, Has something changed regarding the useDynLib in the NAMESPACE file in packages? I've written a package that works in e.g. 2.12/2.13 but simply cannot find the dynamic library under windows. The version on CRAN is older than the one I'm talking about and depends on a newer version of R but I want to make the package available to people with older versions. >

I am considering a package with a namespace (Rgraphviz from Bioc). I essentially want to have some error handling for loading the dll, something like wrapping it into tryCatch or similar (reason: see below). Right now I am loading the dynamic libraries by useDynLib in my NAMESPACE file. When I look at the code from loadNamespace, I have the impression that what I want is impossible

Hello! I am truing to compile an R-package having c-code. I put foo.c in src/ folder and useDynLib("foo") in NAMESPACE file. When trying R CMD check, I got an error message that shared object 'foo' is not found. Then I did R CMD SHLIB foo.c first. However, after that, I got warnings from R CMD check that there is an object file in /src folder. Even worse is if I run R CMD

I have multiple servers running stock CentOS 7 rsyslog 7.4.7-16.el7, which are configured to log locally and over TCP to a remote logserver, also running stock CentOS 7 rsyslog. The remote server uses imptcp to receive, and pretty basic rules to parse and commit to disk. I have several systems that log prolifically, but periodically, they stop soon after the remote log server HUPs (daily

Hi, I'm using LLVM to convert expressions to native assembly, the problem is when LLVM compiles this code: define void @fn_0000000000000000(i8*, i8*, i8*) { bb: %res = alloca i32 %3 = load i32* %res %4 = bitcast i8* %0 to i32* %5 = load i32* %4 %6 = bitcast i8* %0 to i32* %7 = load i32* %6 %8 = xor i32 %5, %7 store volatile i32 %8, i32* %res %9 = load i32* %res %10 = icmp

Hi, I wonder whether a package with namespace & dynamic library can be installed with the version number attached, ie. with the argument --with-package-versions. Is this currently possible? Using R 1.9.1 on Debian 3.0 I encounter a problem when trying to load a package installed with R91 CMD INSTALL --with-package-versions -l /mnt/local/R/R-1.9.x-libs-EpiR RIO in R started with R91

Registration of 'native routines' (entry points in compiled code loaded into R) has been available for over 14 years, but few packages make use of it (less than 10% of those on CRAN with compiled code). Registration has similar benefits to name spaces in R code: - it ensures that the routines used by .C, .Call etc are those in your package (without needing a PACKAGE argument). - it

Now I try to add some C and Fortan code to my package, so the NAMESPACE file is useDynLib(eha) importFrom(survival, Surv) export(mlreg.fit, risksets) but I get ..... * checking R files for library.dynam ... OK * checking S3 generic/method consistency ... WARNING Error in .try_quietly({ : Error in library(package, lib.loc = lib.loc, character.only = TRUE, verbose = FALSE) :

I am writing my first R package, and I have been getting the following series of errors when I run R CMD check: * checking S3 generic/method consistency ...

Hi all, Looking at the body for the function rnorm, I see that the body of the function is: .Call(C_rnorm, n, mean, sd) I want to implement functions that generate normal (and other) random variables. Now, I understand that I can perfectly well just call the R wrapper for these functions and that will be almost indistinguishable for most purposes, but for whatever reason I wanted to try and

I have a package that I'm developing that I need to unload the library. Long story short I figured out that the leaving the compiled code loaded lead to a segmentation fault, but unloading the code will fix it. I've read the documentation and it appears that there are several ways to do this? What is the popper accepted current standard for unloading compiled code? The options as I

hi! I tried to build a very simple package with NAMESPACE file, such that datasets are loaded only dynamically. > a2 <- function(x=a1) x+4 > a1 <- 1:10 > package.skeleton("aaa", list=c("a1", "a2")) Then I modified the help files and added the file NAMESPACE with these 2 lines: useDynLib(aaa) export(a1, a2) Then "R CMD BUILD aaa" works

Hi everybody, I'm trying to develop an R package with Fortran and OpenMP. I wrote a simple hello world but I'm not able to set the number of threads. I found this old email chain <http://r.789695.n4.nabble.com/Set-the-number-of-threads-using-openmp-with-C-td2284685.html> and I tried to set my compile instructions accordingly but i had no luck. *This is my makevars:*

I'm having a little trouble building a package with a namespace. Suppose I have two functions: g and f and I want to build the package foo. Suppose f is a function that has an internal purpose and should not be visible to the user. Additionally, I do not want to write a help (Rd) file for f. The only function that should be visible to the user and have an associated help function is g. First

Gabriel, Thanks for that! I guess I really should have figured that one out sooner, huh? I understand why that wouldn't be CRAN-compliant. But then, what *is* the proper way to do it? Is there any way I can call unexported functions from another package and have it accepted by CRAN? Also, if I instead re-write the random variable generating functions, do you have any idea of where the

Hi everyone, I have been attempting to build a very simple R package interfacing with some very simple C++ code. Everything I try though results in the function working but on return it produces a memory error. Here is the output: ***********OUTPUT*************************** > library(MyPackage) > hello(); *** caught segfault *** address 0x3, cause 'memory not mapped'

Hola, Estoy creando un paquete de R que incluye código C++. Lo he instalado tanto en Linux (Fedora) como en Windows y todo funciona correctamente. El código C++ lo cargo desde el NAMESPACE utilizando useDynLib. Así que ahora estoy revisándolo por última vez antes de someterlo al CRAN. Lo que pasa es que he leído en http://cran.r-project.org/doc/manuals/R-exts.html#Writing-portable-packages
