"linnet"
representing
a linear network.x
.
See unitname
.fatal=TRUE
) or a warning
(fatal=FALSE
).linnet
.
Default is to keep the same representation as in X
.as.linnet
the value is an object of class "linnet"
.
For other functions, see the help file for the corresponding
generic function.as.linnet
is generic.
It converts data from some other format
into an object of class "linnet"
.
The method as.linnet.lpp
extracts the linear network
information from an lpp
object. The other functions are methods for the generic commands
as.owin
,
as.psp
,
pixellate
,
print
,
summary
,
unitname
,
unitname<-
,
vertices
,
volume
and Window
for the class "linnet"
.
The methods as.owin.linnet
and Window.linnet
extract the window containing
the linear network, and return it as an object of class "owin"
.
The method as.psp.linnet
extracts the
lines of the linear network as a line segment pattern (object of class
"psp"
).
The method vertices.linnet
extracts the vertices (nodes)
of the linear network. The function vertexdegree
calculates
the topological degree of each vertex (the number of lines
emanating from that vertex) and returns these values as an integer
vector.
The method pixellate.linnet
applies as.psp.linnet
to convert the network to a collection of line segments,
then invokes pixellate.psp
.
