FINAL RESULTS:

data/r-cran-clue-0.3-57/src/assignment.c:98:9:  [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).
    f = fopen(file,"r");
data/r-cran-clue-0.3-57/src/assignment.c:121:8:  [1] (buffer) fgetc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	    c=fgetc(f);
