http://cran.r-project.org/web/packages/numDeriv
This package provide 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.
