The encoding of colour can be handled in many different ways, using
    different colour spaces. As different colour spaces have different uses,
    efficient conversion between these representations are important. The 
    'farver' package provides a set of functions that gives access to very fast
    colour space conversion and comparisons implemented in C++, and offers 
    speed improvements over the 'convertColor' function in the 'grDevices' 
    package.

An R interface to the C 'libstemmer' library that implements
  Porter's word stemming algorithm for collapsing words to a common
  root to aid comparison of vocabulary. Currently supported languages are
  Danish, Dutch, English, Finnish, French, German, Hungarian, Italian,
  Norwegian, Portuguese, Romanian, Russian, Spanish, Swedish
  and Turkish.

Dr Martin Porter (2001) and Richard Boulton (2004, 2005) for
the 'libstemmer' C library, and Milan Bouchet-Valat (2013) for
the R package contents.
