Class "neigh" Neighborhood characteristics

Description

This class contains the neighborhood which describes the way samples are selected around a target location, when performing an estimation (or a simulation)

Objects from the Class

Objects can be created by calls of the form new("neigh", ...). Neighborhood characteristics

Slots

ndim:

Object of class "numeric" Space dimension

type:

Object of class "numeric" Type of neighborhood. It indicates the type of neighborhood to be used:

0 for Unique Neighborhood: all the active data are selected
1 for Bench Neighborhood: all the active data lying within a slice centered on the target are selected
2 for Moving Neighborhood: only the active data located in the vicinity of the target are selected.
3 for Image Neighborhood: only the samples belonging to a vicinity (defined in terms of cells) around the target grid nodeare used.

flag.sector:

Object of class "logical" Specify if a sector search must be performed (specific to Moving neighborhood)

flag.aniso:

Object of class "logical" Specify if an anisotropic search must be performed (specific to Moving neighborhood)

flag.rotation:

Object of class "logical" Specifiy if the rotated anisotropic ellipsoid must be defined

flag.continuous:

Object of class "logical" Specify if the continuous option is used in moving neighborhood

nmini:

Object of class "numeric" Minimum number of points in the neighborhood (specific to Moving neighborhood)

nmaxi:

Object of class "numeric" Maximum number of points in the neighborhood

nsect:

Object of class "numeric" Number of angular sectors

nsmax:

Object of class "numeric" Maximum number of selected samples per angular sector

width:

Object of class "numeric" Vertical width

dmax:

Object of class "numeric" Maximum isotropic search radius

dist.cont:

Object of class "numeric" Normalized distance beyond which the weights are tapered down

coeffs:

Object of class "matrix" Anisotropic coefficient

rotmat:

Object of class "matrix" Rotation matrix

radius:

Object of class "matrix" Radius of image neighborhood

skip:

Object of class "numeric" Skipping ratio in the image neighborhood
