Error in max(eigen(t(m) %*% m)$val) : invalid 'type' (complex) of argument

[Nicolas Mattia]

I'm failing to run the tests inline-r 0.9.2 with GHC 8.4.3 and R 3.4.3:

Reproduce with the following:

let
  owner = "NixOS";
  repo = "nixpkgs-channels";
  rev = "c06f5302f63af92c9ba0e10401f366e0c7bd7d49";
  nixpkgs = fetchTarball {
      url =
        "https://github.com/${owner}/${repo}/archive/${rev}.tar.gz";
      sha256 = "01fnr797a6iv3cy8gmddmm5gdlrijjdm66y9v14jai3np8fx1nyz";
    };
in (import nixpkgs {}).haskellPackages.inline-r

and run nix-build.

The issue seems because of non-total isolation of the tests here, if I try to run following tests in R itself, it fails:

[nix-shell:~/workspace/tweag/HaskellR/inline-r]$ cat tests/shootout/mandelbrot-noout.R tests/shootout/spectralnorm-math.R | R --slave

Fixed in 6873b81 . It's not in master yet trying to make CI pass for other issues.

Fix is on master
