Hi Folks, I don't think I'm up to implementing a function for drawing French Curves, as requested by "dream". However, the discussion about it took me back so vividly to the old days that, paranormally, I felt once again the urge to ascertain magnitudes as it used to be, and should be, done. I have therefore implemented, and hereby donate to the R community, a new function

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

Hello all, I've got a large set of data consisting of 2 continuous numerical variables, and 2 factors. I'm trying to write a function that will draw scatter plots of the 2 numerical variables for various combinations of the factors. The problem is that my function doesn't seem to understand what I want it to do even though the command works fine outside the function. Here is

I have made available the work of the last weekend that I mentioned in my previous messages on ftp://sirio.stat.unipd.it/pub/R. Many thanks to Peter D. and Ross I. for their suggestions. If you think that the work is of some interest, I can upload it to CRAN. guido m. This is the README enclosed in the distribution. -------------------------------------------------------------------------

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, 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

Running on an Alpha machine which reports (uname -a) OSF1 bsdx01.bs.ehu.es V4.0 878 alpha and using the binary distribution put together by Albrecht Gebhardt (in http://cran.at.r-project.org/bin/osf/osf4.0/tar/alpha_ev5/) I obtain core dumps whenever I try to use package rpart. I have R REMOVE'd the rpart package, downloaded the source rpart_1.0-7.tar from CRAN and

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

(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:

(I dithered a bit about whether this belongs on r-help (as part of it is a general R question) or r-devel (as it's a question relating to putting stuff on CRAN) but decided it might be of general enough interest to go on the former ) I am currently preparing an R library to estimate approximate posterior distributions for parameters in Generalised Linear Mixed Models by Gibbs Sampling

Does anyone know what exactly S_alloc() does? (Yes, it's porting time again ...)

Hello All, I recently upgraded from R-1.1.1 to R-1.2.2. I have an R function that uses .Call() to return a list from C code. The C code has the form: SEXP function(SEXP var) { SEXP rlist ; PROTECT(rlist = NEW_LIST(3)) ; VECTOR_PTR(rlist)[0] = NEW_INTEGER(1) ; VECTOR_PTR(rlist)[1] = NEW_STRING(1) ; ... UNPROTECT(1) ; return(rlist) ; } When I try to

Hmm... I have the same problem on hpux10.20. I put the additional libs into a subdir called contrib, and R INSTALL from there. I have R-0.61.1 Alpha Dec21 1997. Without restored data they work OK.

Hello, I recently switch over from Splus to R and I have not been able to generate right axis labels that face inwards. This is accomplished in Splus with the command srt=270 but this option is not supported in R. In addition the par argument las=0 or 3 does not rotate the right axis labels. The editor of a journal is demanding that the right axis labels face inwards in the figures I recently

Hi, I've restarted my Elsa/LLVM project after three months of having real life intrude. I upgraded my LLVM source to the current trunk. I had to make a few changes to my source, e.g. LLVMFoldingBuilder became IRBuilder and several instances of "new" became "Create". Now, a test case that previously succeeded fails. I run the following script: #!/bin/sh if [ 1 -ne 0 ]

Dear R-devel, Last week I got several responses to my question about debugging segfaults in my code (original post below). After I changed the S_alloc() calls to Calloc()/Free(), the symptom was gone, but I was told to keep looking. So I did: o Switched to Calloc/Free. Electric Fence did not find any problem. o Put assert(index < bound); assert(index >=0); everywhere in the C routine

The R core team proudly presents: \||||||||/ -R 0.61.1- /||||||||\ I've just rolled together a new patch release. It's available from the Auckland repository now, but please do not get it from there unless you are in a terrible hurry. It should find its way to the main CRAN site in Vienna this evening and then to the rest of the CRAN sites. There's also a
