Hello, everybody, I created a R package which includes C code. But I load this package, and carry out the R function in it. It shows C function is not in load table as follows. Would you tell me what is the problem? Where do I make mistake? Maggie [Previously saved workspace restored] > library(var) Attaching package 'var': The following object(s) are masked _by_

Hello, everybody, Happy New Year! I am a graduate student from Concordia University. I meet a problem when I am working on my thesis. I hope I will get help from you. I have a mathematical model which was already implemented by using R language. However, part of this model includes fixed point iteration algorithm and calculation of large linear equations which n will get to 5000. Because of

R developers, I am trying to understand how symbols are resolved, so that I can configure a package that I contributed to, and so that I can provide guidance to (linux / OSX) users of the package. To be concrete, my package uses the LAPACK Fortran symbol zsysv. This is not in libRlapack, but is defined on my system in the library /usr/lib64/liblapack.so. * I suspect that the reason the symbol is

Hi all, I have a C function, say Cfun, that calls Lapack's DGEMM routine and I need to create a shared library to use Cfun inside R. The C file is the following #include<stdio.h> #include<R.h> #include<R_ext/Lapack.h> void Cfun(double *res, double *X, int *n, int *q) { char *ptr_TRANSA, TRANSA='T', *ptr_TRANSB, TRANSB='N'; ptr_TRANSA=&TRANSA;

Hello, I can't link a c code with Mathlib according to introduction of R manual "Writing R Extensions", page 60. It is written : "It is possible to build Mathlib, the R set of mathematical functions documented in 'Rmath.h?, as a standalone library 'libRmath? under Unix and Windows. (This includes the functions documented in Section 5.7 [Numerical analysis

Dirk, thank you a thousand times. Indeed, src/Makevars was wrong. I modified Makevars so that now looks like the below and the package now compiled and linked properly. CXX_STD = CXX11 PKG_LIBS += $(SHLIB_OPENMP_CXXFLAGS) $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) $(shell ${R_HOME}/bin/Rscript -e "RcppParallel::RcppParallelLibs()") PKG_CXXFLAGS = $(SHLIB_OPENMP_CXXFLAGS) -I../inst/include

Dear helpers, I am trying to create a library which uses some Fortran source files and Lapack and Blas subroutines. The Fortran source files from the original author contain subroutines isamax.f, sgefa.f and sgesl.f, which are part of BLAS subroutines on my Linux computer, but maybe different (old) versions. So in addition to these subroutines, there are other Lapack and Blas subroutines

When I install an R package with cpp codes such as rrcov via CRAN (under R 3.1.1, using no Makevars file and under Ubuntu 14.04 using GCC 4.8), the cpp code is compiled with the -o3 flag (in fact, looking at the Makeconf file this seem to again be the default since R 3.1.1) But when I install my own package via CRAN it is compiled with the -o2 flag. My questions are what is causing my

Dear all, I have a problem to build a package on Windows XP while there is no problem on Linux. The Makefile is something like: ########### LIBNAME=cts PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) OBJS=file1.o ... file20.o -llapack -lblas $(LIBNAME)$(SHLIB_EXT): $(OBJS) $(SHLIB_LD) $(SHLIB_LDFLAGS) -o $@ $(OBJS) $(FLIBS) clean: @rm -f *.o *.$(SHLIB_EXT) realclean: clean

Hey Everyone, I'm running R 2.4.0 on Debian etch 4.0, and I'm trying to call some LAPACK functions from the C code in my package. Actually, to be honest I'm not really having trouble using commands such as La_dgesv from within my C code, but I do get warning when compiling the package saying: ***.c: In function '***': ***.c:37: warning: implicit declaration of function

Hi, I don't know if I'm sending this to the right place but I've looked throught tens and tens of topics on http://tolstoy.newcastle.edu.au/ and finally found that email address where I can maybe find some help. Well my main goal is to get to use the lapack library within my R package (which can be done using calls from C). But in order to do this I have to create a file src/Makevars

Hello, all, I have the same question as the last mail I sent. I have installed libRmath in my system. But I still can not link Rmath through -lRmath. The whole process is as follow.Is there anybody who is so kind to help me find out the problem? I will appreciate very much.

The following were the replies to my question about using R's LAPACK and other .h files in some of my C programs. From what was said, it appears that buying a ready-made library (MKL = $200, for example) or using CLapack according to the Shumway lecture notes are the best approaches: -------------------------------- >From Andy Liaw: (1) If you just want linear algebra routines in your C

Hello, everybody, I met a big problem. What I want is to use c code in R. I have load a test code "conv.c" in R and run it successfully. However, in my real code, I use matlab c library (Matrix Inverse function). After I use command "R CMD SHLIB" to share library, I can not use "dyn.load" to load the object in R. "undefined symbol:

Hi, I am working on a UNIX machine and I am interfacing R and C with the .C function. I am trying to call LAPACK and BLAS routines, but am running into a problem where, while I am able to run the BLAS routines, I cannot run the LAPACK routines. I compile my .c file (at end of email) in the following way: [mhitczen at jlogin2 ~/Cstuff]$ R CMD SHLIB testmore.c gcc -std=gnu99

When I build one of my packages with alpha from yesterday I am getting * checking for portable use of $BLAS_LIBS ... WARNING apparently missing $(FLIBS) in 'PKG_LIBS=$(LAPACK_LIBS) $(BLAS_LIBS)' Is this something I should worry about? (Possibly I got this before and didn't notice.) Paul Gilbert ====================================================================================

I am interested in tapping into LAPACK functionality directly from R. Using R-2.4.1 for Windows, I was able to do so ala: dyn.load("bin/Rlapack.dll") is.loaded("dstebz") # returns TRUE N <- 100 NW <- 4 n.tapers <- 5 tpW <- (2 * pi * NW)/N otNmo <- 1:N D <- as.double(cos(tpW) * ((N - 1 - 2 * (0:(N - 1)))/2)^2) E <- as.double((otNmo * (N - otNmo))/2) z

Dear all, I am running R : Copyright 2005, Version 2.2.1 (2005-12-20 r36812) ISBN 3-900051-07-0 On a mac 10.4.5 I am having trouble with my package. The trouble is the following: In my package I have integrated three files in my src folder. 1- simplematch.C a .C file 2- ordering.f a fortran file 3- Makevars : PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) I am not sure if that last file is

I want to use R function Matrix inverse in my c code, please tell me how I can. If there is a sample which can tell me how it works. It will be fantastic.
