I think the first question should be how to build a R function to call a bunch of C ,C++ which include one main program, and a makefile. My goal to build a R package will be next step.
 
I read Rcpp , I am not sure if  RcppResultSet can solve my problem or other function. Once I make sure it work I need ask UNIX adminstrator to install it.
 
I think it shouldn't be very complex,  as I know to build a R function easy with one C function.
 
Thanks you for yout attention!

When you asked _that exact same question_ this morning on r-help, you got the
following answer:

   Pick up Rcpp, make your life easier.

Now, can you let us know 

    a) what part of the answer was unclear to you, and 

    b) what made you think you needed to repost _the identical question_ here

| Thank you in advance!

You're welcome.
