Apply Vector Translation To Line Segment Pattern

Description

Applies a vector shift to a line segment pattern.

Usage

 ## S3 method for class 'psp':
 shift(X, vec=c(0,0), ...)

Arguments

Details

The line segment pattern, and its window, are translated by the vector vec.

This is a method for the generic function shift.

Value

Another line segment pattern (of class "psp") representing the result of applying the vector shift.
