FINAL RESULTS:

data/r-cran-pscl-1.5.5/src/IDEAL.c:68:11:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
    ofp = fopen(R_ExpandFileName(*filename1), "a");
