R.H和Rmath.h在本地C程序 [英] R.h and Rmath.h in native C program
问题描述
R.H和Rmath.h的头文件R.app和C.但之间的接口,他们似乎只能通过R指令是可读的'R CMD SHLIB something.c
"R.h" and "Rmath.h" are header files for an interface between R.app and C. But, they seems to be readable only through a R command 'R CMD SHLIB something.c'
我希望编译我的原生的C程序,包括他们使用gcc。我使用雪豹的地方,我无法找到这些头文件!
I wish to compile my native C program to include them using gcc. I'm using Snow Leopard where I'm not able to locate those header files!
任何帮助吗?
推荐答案
请参阅有关细节写作R附加手册,你可以很容易地编译和反对Rmath.h和独立ř数学库的链接 - 但不是相对湿度(您可以通过RCPP / RInside使用但是这是一个不同的故事。)
Please see the 'Writing R Extensions' manual about details, you can easily compile and link against Rmath.h and the standalone R Math library -- but not R.h. (Which you can use via Rcpp / RInside but that is a different story.)
有一些例子左右浮动使用libRmath的,一种是手动本身英寸下面是在Debian软件包 R-mathlib
含有这种独立的数学库中的一个我的船:
There are a number of examples floating around for use of libRmath, one is in the manual itself. Here is one I ship in the Debian package r-mathlib
containing this standalone math library:
/* copyright header omitted here for brevity */
#define MATHLIB_STANDALONE 1
#include <Rmath.h>
#include <stdio.h>
typedef enum {
BUGGY_KINDERMAN_RAMAGE,
AHRENS_DIETER,
BOX_MULLER,
USER_NORM,
INVERSION,
KINDERMAN_RAMAGE
} N01type;
int
main(int argc, char** argv)
{
/* something to force the library to be included */
qnorm(0.7, 0.0, 1.0, 0, 0);
printf("*** loaded '%s'\n", argv[0]);
set_seed(123, 456);
N01_kind = AHRENS_DIETER;
printf("one normal %f\n", norm_rand());
set_seed(123, 456);
N01_kind = BOX_MULLER;
printf("normal via BM %f\n", norm_rand());
return 0;
}
和Linux上您只需建立这样的(因为我放在包中的标准位置的库和头;加上-I和-L根据需要OS X)
and on Linux you simply build like this (as I place the library and header in standard locations in the package; add -I and -L as needed on OS X)
/tmp $ cp -vax /usr/share/doc/r-mathlib/examples/test.c mathlibtest.c
`/usr/share/doc/r-mathlib/examples/test.c' -> `mathlibtest.c'
/tmp $ gcc -o mathlibtest mathlibtest.c -lRmath -lm
/tmp $ ./mathlibtest
*** loaded '/tmp/mathlibtest'
one normal 1.119638
normal via BM -1.734578
/tmp $
