title: 'numDeriv: Accurate Numerical Derivatives'
version: 2022.9-1
doi: 10.32614/CRAN.package.numDeriv
abstract: 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.
