Influence weight

Description

Weight obtained as the polygon of influence

Usage

infl(db, name=db.getname(db,"z",1), nodes = NA, origin = NA, extend = NA,
     dmax = NA, polygon=NA, radix = "Influence", modify.target = db.locmod(),
     plot=FALSE, flag.grid=FALSE,...)

Arguments

db

The db-class on which the weight must be calculated

name

Each node (of the grid) within a polygon of influence will receive the value of this variable measured at the data point.

nodes

Number of nodes of the discretization grid

origin

Origin of the discretization grid

extend

Extension of the discretization grid

dmax

Maximum distance between data and target

polygon

Polygon limitating the area where the Influence Polygons must be calculated

radix

Radix given to the output weight variable

modify.target

Decides whether or not the newly created variables will have their locator defined or not. For more information, see db.locmod.

plot

When TRUE, the result is shown graphically.

  • When flag.grid=TRUE, each node of the discretized grid is represented with the index of the closest sample,

  • When flag.grid=FALSE, each sample of the data db-class is represented with a symbol proportional to the surface of influence.

flag.grid

When TRUE, the result is the discretized grid. Otherwise, it is the input Data db-class.
