as.layered: Convert Data To Layered Object

Description

Converts spatial data into a layered object.

Usage

as.layered(X)
 "as.layered"(X)
 "as.layered"(X)
 "as.layered"(X)
 "as.layered"(X)
 "as.layered"(X)
 "as.layered"(X)

Arguments

X

Some kind of spatial data.

Value

An object of class "layered" (see layered).

Details

This function converts the object X into an object of class "layered".

The argument X should contain some kind of spatial data such as a point pattern, window, or pixel image.

If X is a simple object then it will be converted into a layered object containing only one layer which is equivalent to X.

If X can be interpreted as consisting of multiple layers of data, then the result will be a layered object consisting of these separate layers of data.

• if X is a list of class "listof" or "solist", then as.layered(X) consists of several layers, one for each entry in the list X;
• if X is a multitype point pattern, then as.layered(X) consists of several layers, each containing the sub-pattern consisting of points of one type;
• if X is a vector-valued measure, then as.layered(X) consists of several layers, each containing a scalar-valued measure.

   as.layered(amacrine)

   P <- rpoispp(100)
   fit <- ppm(P ~ x+y)
   rs <- residuals(fit, type="score")
   as.layered(rs)
