asVector Coerce an Object to a Vector

Description

This is a generic function. Methods for this function coerce objects of given classes to vectors.

Usage

asVector(object)

Arguments

object

An object.

Details

Methods for vector coercion in new classes must be created for the asVector generic instead of as.vector. The as.vector function is internal and not easily extended. Currently the only class with an asVector method is the xyVector class.

Value

a vector
