Just my 2 cents: it may not be a good idea to restrict software
versions to gain reproducibility. To me, this kind of reproducibility
is "dead" reproducibility (what if the old software has a fatal bug?
do we want to reproduce the same **wrong** results?). Software
packages are continuously evolvin

Hi,
In support of reproducible research at my Institute, I seek an approach to
re-creating the R environments in which an analysis has been conducted.
By which I mean, the exact version of R and the exact version of all packages
used in a particular R session.
I am seeking comments/criticism o

Just the fact that it's compiled with such
Hello,
I'm creating a package for R. This package containes a fortran (wrapped C)
*.so .
This dynamic library is compiled to be multi-threaded (-parallel -openmp
-threads .. options).
When I call this library from R : dyn.load("mylib.so")
the execution is one threaded !
Where could be a problem
