• Dirk Eddelbuettel: RcppFastAD 0.0.1 and 0.0.2: New Package on CRAN!

  James Yang and I are thrilled to announce the new CRAN package RcppFastAD which arrived at CRAN last Monday as version 0.0.1, and is as of today at version 0.0.2 with a first set of small updates.

  It is based on the FastAD header-only C++ library by James which provides a C++ implementation of both forward and reverse mode of automatic differentiation in an easy-to-use header library (which we wrapped here) that is both lightweight and performant. With a little of bit of Rcpp glue, it is also easy to use from R in simple C++ applications.
