My approach would be to write a small C++ test function and main program
against the C++ library you use, and run it in both 32 and 64 bit.
Without using R. You then know whether the difference you see is due to the
library, or your R wrapping, which should give you an idea about where to
make ch
i am developing a little package that basically is a simple wrapper around
some C++ code, that is being called via the RCpp package. Basically the
code works, but i did find out that the results are different for 32bit and
64bit environments, so this might point to problems in the C++ code. The
32b
