Extract or replace some entries in a list of spatial objects, or extract a designated sub-region in each object.
# S3 method for solist
[(x, i, …) # S3 method for solist
[(x, i) <- value
An object of class "solist"
representing a list of
two-dimensional spatial objects.
Subset index. Any valid subset index for vectors in the usual R sense,
or a window (object of class "owin"
).
Replacement value for the subset.
Ignored.
Another object of the same class as x
.
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.
