how to get access to C++ Objects
In the "Writing R Extensions" manual appears this example, to get access to C++ function using the R commands:
R> dyn.load(paste("X", .Platform$dynlib.ext, sep = ""))
constructor Y
R> .C("X_main")
constructor X
destructor X
list()
That gives me access to the function "X_main", but how to get access to methods and properties like X.Z() and X.f, defined in the C++ files:
// X.hh
class X
{
public:
int f;
X ();
~X ();
int Z(int a, int b);
};...

...C , we know it.
However It says to use c++ with R , we must :
"
You need to do two things:
(a) Write a wrapper to export the symbols you want to call from R as extern "C".
(b) Include the C++ libraries in the link to make the DLL. Suppose X.cc contains your C++ code, and X_main.cc is the wrapper, as in the example in `Writing R Extensions'. Then build the DLL by (gcc)
...\bin\R CMD SHLIB X.cc X_main.cc
or (VC++, which requires extension .cpp)
cl /MT /c X.cpp X_main.cpp
link /dll /out:X.dll /export:X_main X.obj X_main.obj
or (Borland C++, which also...

A problem with R CMD SHLIB
Hi,
I followed the example in "Writing R Extensions" to create a shared
object in Windows, using the command
R CMD SHLIB X.cc X_main.cc
This was encountered:

FW: [Rcpp-devel] Question on 5.6 Interfacing C++ code
...sent my question about using R and C++ to the wrong list,
ironically seeing as that list was called Rcpp. Anyway, I was directed to
post my question here. To summarize my current question, I have found two
commands that I want to be able to put into a package. The commands are 'R
CMD SHLIB X.cc X_main.cc' and
'dyn.load(paste("X",.Platform$dynlib.ext,sep="")),' which I would like to
run when my package is installed and maybe have the second command run again
when my package is to be used. I've been trying to figure out the
documentation and learn through exampl...

Help on interfacing C++ with R
Hi, I am trying to set up a C++ library for my R code. I followed the
R-extension manual but found out that the example of "X.cpp, X_main.cpp"
is somewhat too simple. Here is my code:
//lib4R.h testing for interfacing C++ with R -- using C++ library in R
#include <iostream>
using namespace std;
class lib4R {
public:
lib4R();
~lib4R();
int testIntDivision(int, int);
double testDoubleMult...
