##### Convert Data To Layered Object

Converts spatial data into a layered object.

Keywords
manip, spatial
##### 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.
##### 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.

##### Value

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

layered, split.ppp
