"""Interpolation Methods.
|
|
|
|
Bivariate data interpolation on regular and irregular grids, either linear
|
|
or using splines are the main part of this package. It is intended to
|
|
provide FOSS replacement functions for the ACM licensed akima::interp and
|
|
tripack::tri.mesh functions. Linear interpolation is implemented in
|
|
interp::interp(..., method="linear"), this corresponds to the call
|
|
akima::interp(..., linear=TRUE) which is the default setting and covers
|
|
most of akima::interp use cases in depending packages. A re-implementation
|
|
of Akimas irregular grid spline interpolation (akima::interp(...,
|
|
linear=FALSE)) is now also available via interp::interp(...,
|
|
method="akima"). Estimators for partial derivatives are now also available
|
|
in interp::locpoly(), these are a prerequisite for the spline
|
|
interpolation. The basic part is a GPLed triangulation algorithm (sweep
|
|
hull algorithm by David Sinclair) providing the starting point for the
|
|
irregular grid interpolator. As side effect this algorithm is also used to
|
|
provide replacements for almost all functions of the tripack package which
|
|
also suffers from the same ACM license restrictions. All functions are
|
|
designed to be backward compatible with their akima / tripack
|
|
counterparts."""
