calcRadius_cpp: Compute geometric caracteristics of a spatial group
Description
C++ function that computes the barycenter of a spatial group. For internal use.
Usage
calcRadius_cpp(coords, sample, threshold, subset_bary, verbose)
Arguments
coords
the spatial coordinates of the observations. matrix with a number of rows equal to the length of sample.
sample
the weight of each voxel in the computation of the barycenter. positive numeric.
threshold
observations with a sample value below the value of threshold are discarded. numeric.
subset_bary
an indicator of the observations that should be kept ? logical vector.
verbose
should the radius of the spatial group be printed ? logical.
