Hi, Paul.
I maintian the rzmq project.
love to get it running on windows, but zmq doesn't play nicely with R's
mingw.
These guys have taken the approach of building the entire zmq library

Can anyone share some opinions on test suites for R packages?
I'm looking at testthat and RUnit. Does anyone have strong opinions on
either of those.
Any additional packages I should consider?

Romain,
Is the use of UNPROTECT_PTR discouraged? I wonder why you haven't
considered using it instead.
I have a similar project that uses a ref counting scheme and handles
the deletion of the shared object with UNPROTECT_PTR. This method has
been working fine, but if there are reasons I should

I've had success w/ using a reference counting paradigm in which the outside
memory manager calls UNPROTECT_PTR(R_object_); in its destructor.
So, in my case (using c++ ) if objects are allocated on the heap, which
allocate R objects as their backend storage, I don't have to worry about out

if you are using external pointers, then R allows you to set a
finalizer function to be called on the pointer.

see examples in RODBC package.
and here too:
see the "connFinalizer" function

If you are in control of the c++ library (i.e. it is not from a
vendor), then you can also override the new operator of your object so
that it allocates an SEXP. if you implement PROTECT/UNPROTECT calls
correctly, then GC will not be a problem.

I have a package that takes about 20 minutes to compile which tends to
prolong the compile/test/compile cycle.
Does anyone know how to get R CMD check or R CMD INSTALL to use parallel make?
I looked at R CMD INSTALL --help, but I don't see anything obvious
arguments to do this.

sorry, for joining this thread so late. I've just upgraded to R2.8.0

Has any consensus been reached about how to deal with this issue?
Do I understand correctly that the change to use:

Is this a bug, or have I misunderstood the proper use of lm?
