Extract.solist: Extract or Replace Subset of a List of Spatial Objects

In spatstat.geom: Geometrical Functionality of the 'spatstat' Family

Extract or Replace Subset of a List of Spatial Objects

Description

Extract or replace some entries in a list of spatial objects, or extract a designated sub-region in each object.

Usage

  ## S3 method for class 'solist'
x[i, ...]

  ## S3 replacement method for class 'solist'
x[i] <- value

Arguments

x	An object of class "solist" representing a list of two-dimensional spatial objects.
i	Subset index. Any valid subset index for vectors in the usual R sense, or a window (object of class "owin").
value	Replacement value for the subset.
...	Ignored.

Details

These are methods for extracting and replacing subsets for the class "solist".

The argument x should be an object of class "solist" representing a list of two-dimensional spatial objects. See solist.

For the subset method, the subset index i can be either a vector index (specifying some elements of the list) or a spatial window (specifying a spatial sub-region).

For the replacement method, i must be a vector index: the designated elements will be replaced.

Value

Another object of the same class as x.
