Hi,
Is this sufficient?

Or is it better to test something in R.version, say os?

Hi,
I'm trying to create a package that contains reference class
definitions from which users can create reference objects, but there
seems to be something awry.
My toy example creates an empty package via
package.skeleton('TestClass') to which I add the following R code:

Apparently reference classes must be declared in the NAMESPACE file
via an S4 declaration. If I place the following in the NAMESPACE file
all is well:

Thought I'd try and start a discussion. Feel free to jump in.
I guess R needs to strike the right balance between opening up the
internals to package writers and not allowing them to do bad things. My
first attempt at cracking this nut is to just memcpy() the Rconnection
and not allow access to
Here's a function to create new connections. It returns and SEXP that
can be returned to R code, but before that, the user can set up all the
function pointer members via passing in the address of an Rconnection.
Here's how you'd call it:
SEXP newcon;
Rconnection conptr;
newcon = R_NewConnecti
I've implemented an R Connections API for packages writers and those
embedding R into other systems. The patch is here:

and I've started an R wiki for discussion here:

Looks like a benign copy-paste issue. This is in R_newurl, and I doubt
anyone would miss that one byte, though.
