shift.psp: 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

X
Line Segment pattern (object of class "psp").
vec
Vector of length 2 representing a translation.
...
Ignored

Value

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

synopsis

## S3 method for class 'psp': shift(X, \dots)

Details

The line segment pattern, and its window, are translated by the vector vec. This is a method for the generic function shift.
