R: Lengths of Line Segments

lengths.psp {spatstat}

R Documentation

Lengths of Line Segments

Description

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

Usage

  lengths.psp(x, squared=FALSE)

Arguments

`x`	A line segment pattern (object of class `"psp"`).
`squared`	Logical value indicating whether to return the squared lengths (`squared=TRUE`) or the lengths themselves (`squared=FALSE`, the default).

Details

The length of each line segment is computed and the lengths are returned as a numeric vector.

Using squared lengths may be more efficient for some purposes, for example, to find the length of the shortest segment, sqrt(min(lengths.psp(x, squared=TRUE))) is faster than min(lengths.psp(x)).

Value

Numeric vector.
