abstract: Nonparametric (and semiparametric) kernel methods that seamlessly handle
  a mix of continuous, unordered, and ordered factor data types. This package is a
  parallel implementation of the 'np' package based on the 'MPI' specification that
  incorporates the 'Rmpi' package (Hao Yu <hyu@stats.uwo.ca>) with minor modifications
  and we are extremely grateful to Hao Yu for his contributions to the 'R' community.
  We would like to gratefully acknowledge support from the Natural Sciences and Engineering
  Research Council of Canada (NSERC, <https://www.nserc-crsng.gc.ca/>), the Social
  Sciences and Humanities Research Council of Canada (SSHRC, <https://www.sshrc-crsh.gc.ca/>),
  and the Shared Hierarchical Academic Research Computing Network (SHARCNET, <https://sharcnet.ca/>).
  We would also like to acknowledge the contributions of the 'GNU GSL' authors. In
  particular, we adapt the 'GNU GSL' B-spline routine 'gsl_bspline.c' adding automated
  support for quantile knots (in addition to uniform knots), providing missing functionality
  for derivatives, and for extending the splines beyond their endpoints.
