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.""" + + cran = "interp" + + version("1.1-3", sha256="b74e606b38cfb02985c1f9e3e45093620f76c0307b1b0b4058761e871eb5fa3f") + + depends_on("r@3.5.0:", type=("build", "run")) + depends_on("r-rcpp@0.12.9:", type=("build", "run")) + depends_on("r-deldir", type=("build", "run")) + depends_on("r-rcppeigen", type=("build", "run")) |
