lengths_psp

Computes the length of each line segment
 in a line segment pattern.

spatial

math

Defines spatial data types and supports geometrical operations
on them. Data types include point patterns, windows (domains),
pixel images, line segment patterns, tessellations and hyperframes.
Capabilities include creation and manipulation of data
(using command line or graphical interaction),
plotting, geometrical operations (rotation, shift, rescale,
affine transformation), convex hull, discretisation and
pixellation, Dirichlet tessellation, Delaunay triangulation,
pairwise distances, nearest-neighbour distances,
distance transform, morphological operations
(erosion, dilation, closing, opening), quadrat counting,
geometrical measurement, geometrical covariance,
colour maps, calculus on spatial domains,
Gaussian blur, level sets of images, transects of images,
intersections between objects, minimum distance matching.
(Excludes spatial data on a network, which are supported by
the package 'spatstat.linnet'.)

lengths_psp function

<dl> <dt>x</dt>
<dd>A line segment pattern (object of class <code>"psp"</code>).</dd> <dt>squared</dt>
<dd>Logical value indicating whether to return
 the squared lengths (<code>squared=TRUE</code>)
 or the lengths themselves (<code>squared=FALSE</code>, the default).</dd></dl>

Arguments

The name of this function has changed from <code>lengths.psp</code>
 to <code>lengths_psp</code>, because the old name <code>lengths.psp</code>
 could be misinterpreted as a method for <code><a href="/link/lengths?package=spatstat.geom&version=3.2-5" data-mini-rdoc="spatstat.geom::lengths">lengths</a></code>.
The older function name <code>lengths.psp</code> is retained temporarily,
 for consistency with older code and documentation. 
In future versions of spatstat, the 
 function name <code>lengths.psp</code> will be removed.
 The newer function name <code>lengths_psp</code> should be used.
