rsaga.inverse.distance
49
Details
Calculation of incoming solar radiation (insolation). Based on the SADO (System for the Analysis
of Discrete Surfaces) routines developed by Boehner & Trachinow.
Value
The type of object returned depends on the intern argument passed to the rsaga.geoprocessor.
For intern=FALSE it is a numerical error code (0: success), or otherwise (default) a character
vector with the module’s console output.
Note
This function uses module 3 from SAGA library ta_lighting.

Spatial Interpolation Methods
Description
Spatial interpolation of point data using inverse distance to a power (inverse distance weighting,
IDW), nearest neighbors, or modified quadratic shephard.
Usage
rsaga.inverse.distance(in.shapefile, out.grid, field,
power = 1, maxdist = 100, nmax = 10,
target = rsaga.target(), saga.version = "2.0.4", ...)
rsaga.nearest.neighbour(in.shapefile, out.grid, field,
target = rsaga.target(), ...)
rsaga.modified.quadratic.shephard(in.shapefile, out.grid, field,
quadratic.neighbors = 13, weighting.neighbors = 19,
target = rsaga.target(), ...)
