similar to: Calling C++ code fom R --How to export C++ "unsigned" integer to R?

Dear ALL-R helpers, I want to let R get vector from c ,for example :numeric array ,vector .I saw some exmple like this : /* useCall3.c */ /* Getting an integer vector from C using .Call */ #include <R.h> #include <Rdefines.h> SEXP setInt() { SEXP myint; int *p_myint; int len = 5; PROTECT(myint = NEW_INTEGER(len)); // Allocating

Hi My code is as follows :- example.h #include"iostream.h" using namespace std; typedef int MYINT; void sum(MYINT a, MYINT b); example.cpp #include"example.h" void sum(MYINT a, MYINT b) { MYINT c; c=a +b; cout<<c; } example.i %module example %{ #include"example.h" extern void sum(MYINT a, MYINT b); %} #include "example.h"

Hi all, myint=function(mu,sigma){ integrate(function(x) dnorm(x,mu,sigma)/(1+exp(-x)),-Inf,Inf)$value } mymu=seq(-3,3,length(1000)) mysigma=seq(0,1,length(500))[-1] k=1 v=c() for (j in 1:length(mymu)) { for (i in 1:length(mysigma)) { v[k]=myint(mymu[j],mysigma[i]) k=k+1 } } Basically, I want to investigate for what values of mu and sigma, the integral is divergent. Is there another way

Hi all, myint=function(mu,sigma){ integrate(function(x) dnorm(x,mu,sigma)/(1+exp(-x)),-Inf,Inf)$value } x=seq(0,50,length=3000) x=x[-1] plot(x,myint(4,x)) # not working yet I think I have to 'Vectorize' it somehow? What's a scalar function? and a primitive function? Thanks. casper ----- ################################################### PhD candidate in Statistics School

Hello, I append another clue I found out: The problem is definitely not caused by "__ImageBase" the problem comes with the "OFFSET". I generated another object file which crashed. The commonality: mov edx, DWORD PTR ?normalPlanschbecken@@3HA ; normalPlanschbecken lea rcx, OFFSET FLAT :??_C at _0CC@LCMJAIPO at Reading?5?$CCnormalPlanschbecken?$CC?5?$CFi@

Hello, I am just a beginner of R 1.9.0. I try to construct a predictive score for the development of liver cancer in cirrhotic patients. So dependant variable is binanry (cancer yes or no). Independant variables are biological data. The aim is to find out a cut-off value which differentiate (theoratically) from normal to pathological state for each biological data. How can I step in procedue to

I wouldn't be surprised if JITing COFF files on Windows doesn't work so well, since the object file format assumes most symbols are dllimport or within the local 2GB module address range. I'm not familiar with the current JIT state of the art, though. On Thu, Mar 22, 2018 at 1:45 AM via llvm-dev <llvm-dev at lists.llvm.org> wrote: > Hello, > > I append another clue I

I am trying to generate my first scaffold but I am getting a 500 error from http://127.0.0.1:3000/foo . Below is the information about my system, as well as the commands I am typing. I have also included the DDL ( Oracle 10g ). I am mid way through chapter 6 of "Agile Web Development w/ Rails". Why aren''t there any files under app/controllers/ ? C:\tmp\rubyWork>ruby

Hi all, Here is an integration function require(pracma) # for 'quadinf' myint=function(j) { quadinf(function(x) (1/(1+exp(-x)))^j*(1-1/(1+exp(-x)))^(k-j)*dnorm(x,mu,casigma),-Inf,Inf) } in any optimization routine. It works fine most of the time but failed with some particular sets of values, say one of the following: k=20 mu=-1.978295 casigma=0.008326927 >

Hello LLVM-Mailing-List, I discovered a strange behavior when dealing with object files generated by the compiler of Visual Studio 2015. When jitting bc files I also add object files to look up functions. These object files are coming from visual studio. When using a switch case instruction that compiler often generates code based of __ImageBase. I show you a short snippet of the assembly

Hi, The optimizer folds "(unsigned int) -1.0f" to 0. As a result, the following routine foo returns 0 with optimization, and returns -1 (0xffffffff) without optimization. unsigned int foo() { float myfloat = -1.0f; unsigned int myint = (unsigned int) myfloat; return myint; } INSTCOMBINE ITERATION #0 on IC: ConstFold to: i32 0 from: %conv = fptoui float

I've noticed the work going on to support namespace and "using" directives. Awesome that this is happening, I've had a couple users wonder about it. (The main issue actually seems to be with anonymous namespaces; gdb will auto-import those declarations, but our debugger doesn't.) I thought I should also bring up another aspect of how Clang/LLVM handles namespaces, in case

Hello everyone, I'm using the LLVM for a JIT-Client under Windows 64bit. I tried various stuff with it and noticed, that object files or libraries which are generated by the Visual Studio Compiler 2015 or 2017 will break the jitted code, when they are added to the process. I opened a bug for this a while ago (https://bugs.llvm.org/show_bug.cgi?id=39447) - sadly this bug will become a stopper

I''m struggling understanding the model view of a combined model. Take the following: class P4 < ActiveRecord::Base has_many :p4_priorities end I figured out the naming and referencing of the sub models (i.e. P4.p4_priorities - seems simple enough but I had weird issues related to it). I''m all ok except that I am having issues with how to reference a

Hi, I want to 'upgrade' from fedora core 1 to centos 3.1, but all of my partitions are reiserfs. The anaconda installer does not give the option to use reiserfs in the disk partitioning portion, is there any way to change this? or should i use a different method to upgrade? Tim.

Dear dev team, I have following question: Microchip is offering IT'S speex library here: http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en023610for it's microcontrollers. Is this a derivate of your sources? If it is, then you should do some checking because I could not find any references to yor credits. Best regards, Marjan --------------
