FINAL RESULTS:

data/r-cran-farver-2.0.3/src/encode.cpp:598:7:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
      strcpy(buffera, col);

  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
