R: Extract or Replace Subset of a List of Spatial Objects

Extract.solist {spatstat.geom} | R Documentation

## 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`.
