[Rd] prototypes for z_sin() and z_cos()

Hi I have been looking at complex.c and want to access z_cos() and z_sin () from C in one of my packages. There doesn't seem to be a corresponding header file: there is no complex.h file. Where are the prototypes of z_sin() and z_cos() for these functions? grepping didn't help me:

[Rd] Compiling R scripts

Dear R Developers, A recommendation for future development. It would help if R scripts could be compiled into an executable, or a library. Speed is the main issue (I run a large scale monte carlo in R which is very slow). However, it would also make it easier to link R into other applications,

[Rd] How difficult is it to wrap a large C++ library with R?

Dear list, I have developed a forward-time population genetics simulation environment simuPOP, which is a set of C++ (template) classes/functions wrapped by SWIG as Python libraries. R is used extensively as plotting and statistical analysis engine through RPy package. I use Python to wrap

Re: [Rd] [R] How to convert c:\a\b to c:/a/b

The readLines example, as written, does not work in sourced files and therefore will not work in the Examples section of .Rd pages either. Currently readLines does not process its input and I think it would not be a good idea to change that philosophy. On 7/4/05, Spencer Graves [EMAIL

[Rd] installing packages and libraries

When I run the following: cd \Rpkgs rcmd install mypackage -l library I get a message that it cannot find quadprog which is a library that mypackage depends on. Error: package 'quadprog' could not be loaded I previously used C:\Program Files\R\rw2011\library as my library for CRAN

Re: [Rd] How difficult is it to wrap a large C++ library with R?

* Wrap C++ class hierarchy. Virtual functions need to be supported. (SWIG can generate Python shadow classes that behave almost exactly like the underlying C++ classes) This is hard to do in R, because the R object model is quite different from that of C++ (whereas Python's is more

Re: [Rd] How difficult is it to wrap a large C++ library with R?

SWIG is a very nice idea. ... SWIG is a wonderful tool that makes wrapping C++ code super-easy. I can write pure C++ code and even test them by writing a main() function. Then, using a simple interface file, all my C++ classes becomes Python (shadow) classes like magic. It will take much more
