similar to: optim-Bug (PR#6720)

I want to write a little stand-alone C program that calls R_alloc, but I get a segmentation fault: int main(int argc, char** argv){ double* d = (double *)R_alloc(2, sizeof(double)); // <- segmentation fault! return 0; } gdb reveals that sizeof(double) evaluated to 0: > R_alloc (nelem=2, eltsize=0) at memory.c:1649 so it results in the segfault later. This is how I compile my

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

Hi all, Thanks to Prof. Ripley, Prof. Gentleman, and Simon Wood (did I miss anyone?). The problem seemed to have gone away. Everyone suggested using some malloc debugger (such as Electric Fence). All I did was following half of what BDR suggested below, i.e., changing all the S_alloc() calls to Calloc() and Free(). I didn't get to try efence, and the problem seems to have disappeared! As

Hi. If I call the quantiles function as follows: qvec = quantiles(dvals,probs=seq(0,1,0.1)) the results will return a vector something like the following example: 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 56.0 137.3 238.4 317.9 495.8 568.5 807.4 1207.7 1713.0 2951.1 8703.0 Now I want to assign the deciles, 1 - 10, to each

I am trying to get our database interface (PADI) working with R. The code does some memory allocation and for Splus there is an ifdef which controls whether malloc or S_alloc is called. I did nm R.binary | grep alloc to see if this was supported and I find there are some choices: [2490] | 446036| 272|FUNC |GLOB |0 |7 |R_alloc [806] | 693956| 312|FUNC |LOCL |0 |7

Can anyone help me with lbfgsb (function for optimization)? It takes the following parameters: void lbfgsb (int n, int lmm, double *x, double *lower, double *upper, int *nbd, double *Fmin, optimfn fn, optimgr gr, int *fail, void *ex, double factr, double pgtol, int *fncount, int *grcount, int maxit, char *msg, int trace, int nREPORT); What do I put for parameter ex (11th parameter)?

Hi, I have problems when calling fft_factor and fft_work directly in my C-code. Martin Maechler already told me that I should not do this -- anyway, the code works fine if the length of the vector is a multiple of 2,3,5. If the length of the vector has different form I get, in some cases, a segmentation fault when work and iwork are freed (I use C's malloc to allocate memory for work and

Hi I have a FORTRAN version of the L-BFGS-B algorithm and I was comparing it to the code in the lbfgsb.c file available at R-4.0.0.tar.gz Everithing looks the same, except for those two lines that must be printed by the prn3lb function in case of an error (lines 3559 and 3561 in lbfgsb.c): case -5: Rprintf("l(%d) > u(%d).

Hi there , I use clang-cl /Qvec test.c to compile the code. But the pass LoopVectorizer is never invoked. I was wondering if this is sufficient to enable auto vectorizer?

(Sorry for the cross-post--- I wasn't sure which list is more appropriate...) Hi everyone, I've run into segfaults when using my randomForest package on large dataset (e.g., 100 x 15200) and large number of trees (e.g., ntree=7000 and mtry=3000). I'm wondering if anyone can give me some hints on where to look for the problem. The randomForest package mainly consists of two things:
