R: Coerce an Object to a Vector

asVector {splines} | R Documentation

## 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

### Author(s)

Douglas Bates and Bill Venables

### See Also

`xyVector`

### Examples

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