similar to: segmetation fault

I realized that I may not have answered the question you were asking and that no one else has responded. I can across a similar problem and may have an answer to your question now. If you have both the wavelet coefficients and the scaling coefficients then create a fake sequence of the same length as the original and decompose that sequence using wd form wavethersh with the same wavelet family

Hi all, I has a C code in Linux, it has 7 pointers and compile e run OK, but when I run in R happens Segmetation Fault. When I use calloc function, it returns NULL. What's wrong? I would like more information about R-alloc function?

Dear People, I wrote the following bit of C code and (along with other bits) called it mycode.c, and compiled the file into a shared library to load into R, using R CMD SHLIB mycode.c. This was Ok, but when I tried to load this into R using dyn.load("mycode.so") I got the error > dyn.load("mycode.so") Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to

a) you need to read the help pages on the paste function... more likely you are looking for the paste0 function because extra spaces will most likely break the GET request format. b) quotes do not become "stuck" as \" ... that is a visual representation intended to clarify that that quote is not terminating the string but is actually part of it.

Hey, Can anyone answer this question. I am working with really large datasets and most of the programs I have been running take quite some time. I heard that R may be faster in Unix. I sthis true and if so can anyone reccomend which system and requirements may allow things to go faster for? Thanks!! Elizabeth Lawson --------------------------------- [[alternative

hi all - i have a source package i'm writing that i'd like to be able to install with a special library that my R src files rely on. to be more precise, i have a normal R package directory structure (i.e. src/ R/ man/ DESCRIPTION NAMESPACE etc.). i also have another directory here called depPkg, and it has it's own configure file for the canonical './configure && make

Thank you for your help in advance.

Hey eveyone! I hope someone can help wiht this question. I have a matirux of all zeros and ones and I would like to indentify all unique patterns in the rows andthe number of times the pattern occurs. I changed all zeros to NA tried to use prelim.norm to identify all patterns of missing data in the rows. I got the message Warning message: NAs introduced by coercion Any ideas of how

Hey, Does anyone know if there is a way to get back from goodfit what it estimated the parameters to be? I used the code fit<-goodfit(round(data$PLX_NRX),type="nbinomial" and got a pretty good fit. I could not however duplicate this good fit with any parameter estimates that I had. Any ideas??? Thanks, Elizabeth Lawson ---------------------------------

I have tried to invoke a transformation/optimization pass using -mllvm, without success. I might be missing something. For example I have a shared/dynamic library which contains LLVM passes. I used to invoke them with llvmc like this: >>*llvmc mycode.c -o mycode.o -c -opt -Wo,=-load,libFoo.dylib,-Foo* Can this style of optimization be executed using -mllvm argument? Thx, PMon On Sun,

Hi, I have met a tough problem when using PHP to call R to generate some plots. I tested it okay in my personal computer with WinXP. But when I was trying to update to my server (Win2003 server), I found it did not work.

Dear All, I have a database of 200 observations named myD. In the dataframe there are a column named code (with codes varying from 1 to 77), a column named "prevalence" with some quantitative measurements are given and an column named Pr_mean, with no values. I would like to set a cycle to compute the average of prevalence values for each different code and store the averages under the

Dear all, Has anyone seen the same problem? I tried compiling R-1.9.0 alpha (2004-03-16) on our Opteron box running SUSE Linux ES8.

Hi, Has anyone come across this difficulty using R-2.2.1 in Windows XP: when I try to run R CMD SHLIB mycode.c I get the response: "The system cannot execute the specified program." I've tried installing all windows updates, reinstalling R and putting "R-2.2.1\bin" at the head of my path. Googling that error message leads to lots of stuff about *.manifest files. The

Hi, All: I had some trouble debugging C source dynamically loaded into R , when I issued N in gdb(or insight) , the debugger, instead of moving downward step by step, jumped to strange positions (upward, downward, one step, a few steps away). To enter the debugger, I issued gdb(insight) Rgui.exe in Cygwin and add this line : asm("int $3"); to my C code. After entering R, I

hey, I am running R 2.0.1 on a the terminal of my MAC OS X and I have written some C code that I would like to use dynload to bring into R. When I try to compile the code i get the error R.defines.h no such file or directory. I know that the file is in resources/include but where do I have to move the file to so that the compiler can access it? I tried copying Rdefines.h and R_ext folders

Hey, I am estiamting a partially linear model y=X\beta+f(\theta) where the f(\theta) is estiamted using wavelets. Has anyone heard of methods to test if the betas are significant or to address model fit? Thanks for any thoughts or comments.

Hi, I am hoping some one can help me. I am learning to use C and would like to learn how to call c code in R. I have look at Writing R Extensions and I tried to copy the example on page 38 void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++) ab[i] = 0.0; for(i = 0; i < *na; i++) for(j = 0; j <
