Description

Combine two line segment patterns into a single pattern.

Usage

Arguments

Line segment patterns (objects of class "psp").

Value

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

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.
