Extract.solist: 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 solist
[(x, i, …)

# S3 method for 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.

Value

Another object of the same class as x.

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.
