Hi Martin,

in NixOS, there is no way to run any kind of build process in an
environment that has network access. On one hand, that is a security
consideration, but the even more compelling reason for that choice is
that NixOS goes to great lengths to guarantee deterministic builds, and
a build process that connects to servers on the Internet and uses data
they provides is as non-deterministic as it can be, unfortunately.

What we can do for the 3.4.0 release is to extend our build environment
for R to ensure that all required resources are downloaded and made
available locally before the build starts.

Thank you for pointing that out. We do offer our users the choice of
whether they want the recommended packages included or not (the default
choice being to not include them), so we should in fact parameterize our
build to run the extended test suite if the recommended packages are

Another option would be to always build the recommended packages, but to
not install them if the user doesn't want them included. I'm not sure,
though, whether the R build system supports such a type of build easily?

Best regards,
