as.linnet.linim: Extract Linear Network from Data on a Linear Network

Description

Given some kind of data on a linear network, the command as.linnet extracts the linear network itself.

Usage

# S3 method for linim
as.linnet(X, ...)
 # S3 method for linfun
as.linnet(X, ...)
 # S3 method for lintess
as.linnet(X, ...)
 # S3 method for lpp
as.linnet(X, ..., fatal=TRUE, sparse)

Value

A linear network (object of class "linnet").

Arguments

X

Data on a linear network. A point pattern (class "lpp"), pixel image (class "linim"), function (class "linfun") or tessellation (class "lintess") on a linear network.

...

Ignored.

fatal

Logical value indicating whether data in the wrong format should lead to an error (fatal=TRUE) or a warning (fatal=FALSE).

sparse

Logical value indicating whether to use a sparse matrix representation, as explained in linnet. Default is to keep the same representation as in X.
