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

Examples:

     data( women )
     ispl <- interpSpline( weight ~ height,  women )
     pred <- predict(ispl)
     class(pred)
     str(pred)
     asVector(pred)
