hi everybody, anyone knows how we can transform a binary matrix with TRUE and FALSE to 0 and 1 without looping? Thx --------------------------------- [[alternate HTML version deleted]]

Dear R developer, we are trying to build DLL files using Microsoft Visual C++. As stated in readme.packages, we have to build first the import library Rdll.lib with the command: lib /def:R.exp /out:Rdll.lib. However, this command gives 2155 errors due to unresolved external symbols (ATTRIB to zlibversion) in Rexp. Could anybody tell me if something is missing in the command line or suggest any

Is there a way to force certain formula parameters to be nonnegative? What I want to do is to estimate student capacity over time, namely by > capacity ~ Student + Student:Day I add this formula to a glm call and obtain negative learning slope estimates (Student:Day) in some cases. However, I don't want to allow for that. In such a case, glm should solve > capacity ~ Student and

Hi all, and thx a lot for your answers, in fact i know that R deals with logical numbers 0 and 1 the same way like TRUE and FALSE but my problem is in fact with C language. I have done an interface with C and my first problem was with float variables, but this warning doesn't appear everytime and really i don't know the problem with R: "Warning message: DLL attempted to change

Dear all, i was working under R 1.6.2 but i wanted to install bioconductor under WinXP, and because R 1.7.1 contains the TclTk package and automatic installation of bioconductor packages, so i install it. Everything is fine except this message which appear after the installation of packages. "> local({a<- CRAN.packages(CRAN=getOption("BIOC")) +

Hello, I am trying to compile ROracle _0.5-4 under R 1.9.0 without much success. I am running Windows 2000 SP4, Visual C++ 6.0 SP6, and Oracle client 9.2.0.1.0. I was able to run the pre-compiled version of ROracle_0.5-2 under R 1.7.1, but does not work on R 1.8.1 or R 1.9.0. Here is the output from nmake: C:\Program Files\R\rw1090\library\ROracle\src>nmake Microsoft (R) Program

Hello, The procedure for creating an import library (Rdll.lib) that is documented in gnuwin32/README.packages works fine using the i386 architecture, but it doesn't seem to work under x64. Specifically, the procedure is: pexports R.dll > R.exp lib /def:R.exp /out:Rdll.lib /machine:X86 R.dll There are two issues under x64: 1. Older version of pexports crash when applied to an x64 R.dll.

>From the R-2.6.0/doc/README.packages it says: Using Visual C++ ================ You may if you prefer use Visual C++ to make the DLLs (unless they use Fortran source!). The notes here were tested with VC++6. First build the import library Rdll.lib by make R.exp ... In the installation (R-2.6.0-win32.exe) there is no Makefile with an R.exp target that I could find and I get

Hello, I am using cygwin (latest version) and I managed to generate a dll partly with rcmd shlib although there was a problem with both the resouce file (I had to remove "FILEOS VOS__WINDOWS32") and the command line for gcc (--shared is not supported for instance). So I would like to know which compiler/environment you advise to use for windows OS. Then I could load the library in R

Hi everyone, I just landed into the theora planet, as a game programmer, I searched for a free video fomat/codec and the theora choice became obvious. However I experienced rather bad performance (at least from a game programming point of view) After a couple a profiling, I discovered, as previous discused in a post found via Google, that the bottleneck is in the ogg library. An unsane part of the

Dear all, i have a question about the "sample" function used in R, does it work as a pseudo-dandom number generator programmed with C, like it is described in Modern Applied Statics with S-Plus 3d edition chapter 5 section 2?

Hi, I need to use ROracle to communicate with Oracle from R program in windows environment. I am using Oracle 10g, R 2.6.2. I found a pre-compiled binary for ROracle for Oracle version 9.2. When I am trying to use it with Oracle 10g I get the following error: con <- dbConnect(drv, "user/passwd at dbname"); Error in function (classes, fdef, mtable) : unable to find an inherited

Hello, I'm trying to compile a library in MS Visual C++ using R.dll. For that, I need R.lib for linking. Where can I get it? "Readme.packages" for R says: "First build the import library R.lib by lib /def:R.exp /out:Rdll.lib" But for this, I need R.exp, that is also not provided with R installation (Lib.exe output: LIB : fatal error LNK1104: cannot open file

Hi, I wonder where I can find an example of using a function in LAPACK library in a user's own C code. I wrote a C program which will be compiled and linked to produce a DLL file and then loaded into R. I hope to use a function from LAPACK library, for example, dgesdd, in the program. Following R manual, I call the function by F77_CALL(dgesdd) in the program. The program can be compiled

Full_Name: Venkatesh Mysore Version: R-1.7.0 OS: WindowsXP Submission from: (NULL) (216.165.110.10) While accessing Rproxy.dll repeatedly (using the code from the (D)COM example in the R website) causes a failure in the 24th iteration. R-1.6.2 does NOT give this error. This seems to be a memory management error, that might be linked to the huge leakage difference between R-1.7.0 and R-1.6.2

Dear sir\madam! I'm trying to speed up my R code by writing quite simple dll's in C. But I faced some problems, and I cannot determine their source. #include <Rinternals.h> SEXP mycombin(SEXP N, SEXP k){ int i, *j, *l, c; j = INTEGER(k);l = INTEGER(N); c = 1; if(j[0] > 0 && j[0] < l[0]){ if(j[0] <= l[0] - j[0]){ for(i =

Hi, I am new to R. I need to communicate with Oracle from R program in windows xp. So I am planning to use ROracle. I downloaded the ROracle src from the site below: http://cran.r-project.org/web/packages/ROracle/index.html I am using R version 2.6.2 and Oracle 10g. I followed the instructions to build ROracle. When I try to compile the source src/Makefile.win I get the following error:

recently I used gcc 4.9.1 (http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win64/Personal Builds/mingw-builds/)on windows to build R,but failed when link R.dll ,it report linker status 5.  after some digging, I found when use gcc 4.9.1 64 bit on windows there are lots of .refptr.*(* is r function name) in R.def, which lead build fail.so I add a simple path to
