TAKATSU Tomonari 229913f9fd - Add new port: math/R-cran-numDeriv
Methods for calculating (usually) accurate numerical first and
  second order derivatives. Accurate calculations are done using
  'Richardson"s' extrapolation or, when applicable, a complex step
  derivative is available. A simple difference method is also provided.
  Simple difference is (usually) less accurate but is much quicker
  than 'Richardson"s' extrapolation and provides a useful cross-check.
  Methods are provided for real scalar and vector valued functions.
