extrapolate.psp: Extrapolate Line Segments to Obtain Infinite Lines

In spatstat.geom: Geometrical Functionality of the 'spatstat' Family

Extrapolate Line Segments to Obtain Infinite Lines

Description

Given a spatial pattern of line segments, extrapolate the segments to infinite lines.

Usage

extrapolate.psp(x, ...)

Arguments

x	Spatial pattern of line segments (object of class "psp").
...	Ignored.

Details

Each line segment in the pattern x is extrapolated to an infinite line, drawn through its two endpoints. The resulting pattern of infinite lines is returned as an object of class "infline".

If a segment's endpoints are identical (so that it has zero length) the resulting infinite line is vertical (i.e. parallel to the y coordinate axis).

Value

An object of class "infline" representing the pattern of infinite lines. See infline for details of structure.
