R: Influence weight

infl {RGeostats}

R Documentation

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`.
`...`	List of arguments passed to function `db.plot`.

Value

If flag.grid=FALSE, the input db-class with a new variable containing the surface of the polygon of influence attached to each sample.
If flag.grid=TRUE, the discretized grid db-class with a new variable containing the index of the closest sample.
