Knot Vector from a Spline

### Description

Gets the knot vector from a spline.

### Usage

    # Generic function
    splineKnots(object)
    ## S3 method for class 'spline':
    splineKnots(object)

### Arguments

object | any object inheriting from class "spline".

### Details

splineKnots is a generic function to get the knots. Currently, only the invisible method splineKnots.spline is implemented for class "spline". There is no default method.

Examples

    x <- c(1, 2, 3, 8, 20)
    y <- log(x)
    # piecewise polynomial representation has knots at 'x'
    psp <- interpSpline(x, y, bSpline=FALSE)
    splineKnots(psp)
    # B-spline representation has extra knots
    bsp <- interpSpline(x, y, bSpline=TRUE)
    splineKnots(bsp)
