[Rcpp-devel] Loading my own dynamic library using Module ?

[Tama Ma]

Dear Rcpp developers,

I use gcc compiler and manage to compile my Rcpp-wrapped C++ code to /my/project/dir/lib/mod.so .

Now, I want to call it inside R. Is there a way to do something like:
export R_LIBRARY_PATH= $R_LIBRARY_PATH:/my/project/dir/lib

require(Rcpp)
mod <- Module("mod")

Meanwhile, I tried googling around, and looking into the src code, but I haven't got an idea yet.

Is there a fast solution, or may I help a bit?

Thank you very much.

Best regards,
Tama Ma

I think you can use dyn.load:

dll <- dyn.load( "/my/project/dir/lib/mod.so" )
mod <- Module( "mod", dll )

But I would strongly advise you to create an R package to host the code.

An easy way to do this is to use the Rcpp.package.skeleton function.

Dear Romain,

This works perfectly!
Thank you very much.

(PS: Thank you for your advice on moving to R packages, and I will read on how to do that.)
