Rcpp function

Auxiliary functions to count point neighbors

C++ routines used for fast count of neighbors.

parallelCountNbd(r, x, y, Weight, IsReferenceType, IsNeighborType)
parallelCountNbdCC(r, x, y, Weight, IsReferenceType, IsNeighborType)
parallelCountNbdm(x, y, ReferencePoints)
parallelCountNbdDt(r, Dmatrix, Weight, IsReferenceType, IsNeighborType)
parallelCountNbdDtCC(r, Dmatrix, Weight, IsReferenceType, IsNeighborType)
DistKd(x, y, PointWeight, Weight, Dist, IsReferenceType, IsNeighborType)
CountNbdKd(r, x, y, Weight, Nbd, IsReferenceType, IsNeighborType)

Arguments

• r: A vector of distances.
• x: A vector of x coordinates.
• y: A vector of y coordinates.
• Dmatrix: A matrix of distances.
• PointWeight: A vector of point weights.
• Weight: A vector of point weights.
• ReferencePoints: A vector of pont indices.
• Nbd: A matrix to store the weight of neighbors.
• Dist: A vector of point-pair distances.
• IsReferenceType: A boolean vector to recognize reference points.
• IsNeighborType: A boolean vector to recognize neighbor points.
