R: Combine Two Line Segment Patterns

append.psp {spatstat.geom} | R Documentation

## Combine Two Line Segment Patterns

### Description

Combine two line segment patterns into a single pattern.

### Usage

      append.psp(A, B)

### Arguments

`A,B` | Line segment patterns (objects of class `"psp"`).

### Details

This function is used to superimpose two line segment patterns `A` and `B`.

The two patterns must have identical windows. If one pattern has marks, then the other must also have marks of the same type. It the marks are data frames then the number of columns of these data frames, and the names of the columns must be identical.

(To combine two point patterns, see `superimpose`).

If one of the arguments is `NULL`, it will be ignored and the other argument will be returned.

### Value

Another line segment pattern (object of class `"psp"`).

      append.psp(X,Y)
