similar to: pythag missing in src/appl/ROUTINES (PR#544)

Some of you may have seen the pythag() part in the R API definition in "Writing R Extensions" (source = doc/manual/R-exts.texinfo). or followed the report and Prof. Brian Ripley's answer about pythag()'s availability from R's binary. As we say in above manual >> `pythag(A, B)' computes `sqrt(A^2 + B^2)' without overflow or >> destructive

Today I installed the newest R develepment branch R version 2.14.0 Under development (unstable) (2011-03-18 r54866) on FreeBSD 9.0-CURRENT (amd64). All seems fine so far. After that I updated my R packages with option 'checkBuilt=TRUE'. There are four packages (spatstat, pscl, adehabitatLT, adehabitatHR) which gives an error like this: Error in dyn.load(file, DLLpath = DLLpath, ...) :

Dear List, I stepped into a strange effect which I can't explain to myself (probably due to lack of knowledge on R internals). I have four vectors a,b,c and z of size 10000 each. With these vectors I call .Call("hyp2f1forrey", a, b, b, z, PACKAGE = "hyp2f1") to access SEXP hyp2f1forrey(SEXP a, SEXP b, SEXP c, SEXP x) { int i,n; double *xa, *xb, *xc, *xx,

Dear all, I am trying to compile R version 1.0.1 under Solaris on a SUNsparcUltra10. Note that I'm doing this in my home directory as I cannot do it as root. The configure script seems to run correctly and issues as the last few lines: ----------------------------------------------- ... R is now configured for sparc-sun-solaris2.7 Source directory: . Installation directory:

Hi when I call the function below in R, i get the error: Object 'pairlist' can't be converted to 'double'. #include <R.h> #include <Rdefines.h> #include <Rmath.h> SEXP CSimPoisson(SEXP lambda, SEXP tgrid, SEXP T2M, SEXP Ni, SEXP NT) { double sign, EVar; double *xlambda, *xtgrid, *xT2M, *xNi, *xNT, *xtau; SEXP tau; int ltgrid =0; int i = 0; int j = 0;

I've been attemping to create a test dll that contains R objects (actually I simply copied the code from the "Writing R extensions") and got it to build the dll using rcmd shlib main.c (okay, it's simple, but effective). Here's the info so far: this is the contents of the main.c file (not there's no WinMain()). Do we put it in or does the script do it when we compile?

I'm continuing my work on finding speedups in generalized inverse calculations in some simulations. It leads me back to .C and .Call, and some questions I've never been able to answer for myself. It may be I can push some calculations to LAPACK in or C BLAS, that's why I realized again I don't understand the call by reference or value semantics of .Call Why aren't users of

Hi, I've been trying to install R on Solaris, I've been following the instruction for configuring & compiling R (I have gcc and f77 installed)- but I get Error messages. I'd appreciate it if you could look at the output, (pasted below) and give me some advice on what to do. I've attached the R install 'readme'. Thanks, a quick reply would be greatly appreciated,

Dear R-developers, Using .Call I pass a S4 class with e.g. the following class definition: setClass("mmatrix",representation( data="matrix") ) On the "C side" i do mat = GET_SLOT(vs,install("data")); and then: printf("%f\n",NUMERIC_POINTER(mat)[1]); The above print statement produces the correct output if xx<- new("mmatrix")

Hi! I want to return a matrix. The code does the R interfacing. This version does it fine. SEXP ans,dim; PROTECT(ans = NEW_NUMERIC(count*2)); memcpy(NUMERIC_POINTER(ans),result,count*sizeof(double)); memcpy(&(NUMERIC_POINTER(ans)[count]),occur,count*sizeof(double)); /** PROTECT(dim=NEW_INTEGER(2)); INTEGER_POINTER(dim)[0]=2; INTEGER_POINTER(dim)[1]=count;

I use a large real matrix, X, in C code that is passed from R and transposed in place in the C code. I would like to conserve memory and, if possible, allocate space for only one copy of X -- hence I would like to pass a pointer to the data in the X object to the C code. The Writing R Extensions manual says that neither .Call nor .External copy their arguments. They also say that these

Trying to do something like this, in Ubuntu 11.10/12.04: Location A (work occurs changing files) rsync --write-batch /media/bkup/foo.rsb /path/to/files/ /path/to/copy/ Location B rsync --read-batch /media/bkup/foo.rsb /path/to/files/ rsync --read-batch /media/bkup/foo.rsb /path/to/copy/ (work occurs changing files) rsync --write-batch /media/bkup/foo.rsb /path/to/files/ /path/to/copy/

In revising the splancs package, I use R CMD check. After a number of changes to various files in the directory tree, R CMD check fails at the * checking for undocumented objects ... ERROR stage as shown below. But running undoc() in R (pointed at the Rcheck directory, not on the older version) doesn't show the same error, and grep on the Rcheck R code finds the function. I ran undoc() under

Full_Name: Roger Bivand Version: 1.3.0 OS: GNU/Linux RH6.2, 7.0, Debian 2.2 Submission from: (NULL) (158.37.100.64) I'm working on interfacing ANN: A Library for Approximate Nearest Neighbor Searching (http://www.cs.umd.edu/~mount/ANN/) to R, following up a prototype package I tried in May 2000. ANN is written in C++; my C++ is very weak. Last year I didn't experience any problems with

Recent sensible changes to the dynload mechanism have made an old problem resurface: how should we deal with packages which contain Fortran code and may need to be linked against additional libraries such as -lf2c? The current consensus is that extra Fortran libraries maybe needed are handled via the make variable FLIBS, and that `-lf2c' or `-lg2c' are added by default if g77 is used.

Sorry about not being specific enough. I will try and be more so in the future. Here is what I have currently: Apple X-serve running Yellowdog (a Redhat 9 port for ppc) with 1GB of RAM, 3 60GB HD not setup as RAID. They are individual partitions (/var and /, /home and /shared). The shared partition is strictly for Samba file sharing. I build in a matching user in both the system and in

Hello all... Found a weird one here. I tried to search the web but I'm not having luck so I thought I'd hit the mailing list. We have noticed off and on all school year that every so often a user gets an email that they just can't delete using Thunderbird or Outlook over IMAP (we do not support Pop3 anymore.) Essentially the user clicks the email and takes it to the trash.

Hi, I would like to call R's lbfgsb function from my C/C++ code by including R_ext/Applic.h and linking against libR. Currently, I am allocating memory for x (and the other input arrays for lbfgsb) in my C/C++ code via malloc/new. However, this gives a segmentation fault when executing the program. I tried to allocate x via PROTECT(x = NEW_NUMERIC(n)); x_p = NUMERIC_POINTER(x);. This compiles

Greetings, I am trying to call simple C-code from R. I am on Windows XP with RTools installed. The C-function is #include <R.h> #include <Rinternals.h> #include <Rmath.h> #include <Rdefines.h> // prevent name mangling extern "C" { SEXP __cdecl test(SEXP s){ SEXP result; PROTECT(result = NEW_NUMERIC(1)); double* ptr=NUMERIC_POINTER(result); double t =

See https://stat.ethz.ch/pipermail/r-devel/2017-August/074746.html for the origin of the example here. That pretty(c(-1,1)*1e300, n = 1e9, min.n = 1) gave 20 intervals, far from 1e9, but pretty(c(-1,1)*1e300, n = 1e6, min.n = 1) gave 1000000 intervals (on a machine), made me trace through the code to function 'R_pretty' in https://svn.r-project.org/R/trunk/src/appl/pretty.c . *lo is
