[Rd] How to use R and add-on packages as library in C/C++

[Pai-Hsien Hung]

Thanks for your reply.  

  I have already read the manual again, and use the R.dll (Ch 8.2.2) (Am I
right?).  Running the example in the section is OK.  But, when I try to add
"do_matprod" function in the same example, I don't know what args should put
in.  The function description in array.c is SEXP attribute_hidden
do_matprod( SEXP call, SEXP op, SEXP args, SEXP rho), and where I can get
the definition and description of each variables, call, op, args, ....

Thanks,

This is indeed in the manual you mention.  To use R functions and not just 
standalone libRmath, you need to embed R.
