Convert Data on a Network to class owin
Converts data on a linear network
into an object of class "owin".
## S3 method for class 'lpp' as.owin(W, ..., fatal=TRUE) ## S3 method for class 'lppm' as.owin(W, ..., fatal=TRUE)
W |
Data specifying an observation window, in any of several formats described under Details below. |
fatal |
Logical value determining what to do if the data cannot be converted to an observation window. See Details. |
... |
Ignored. |
The class "owin" is a way of specifying the observation window
for a point pattern. See owin.object
for an overview.
This help file documents additional methods applicable when W is
an object of class "lpp"
representing a point pattern on a linear network.
In this case, as.owin extracts the linear network
and returns a window containing this network.
an object of class "lppm"
representing a fitted point process model on a linear network.
In this case, as.owin extracts the linear network
and returns a window containing this network.
If the argument W
cannot be converted to a window, then an error will
be generated (if fatal=TRUE) or a value of NULL
will be returned (if fatal=FALSE).
An object of class "owin"
(see owin.object)
specifying an observation window.
