splinek {asreml} | R Documentation

## Spline knot points.

### Description

Return the spline knot points generated via the `spl()` model function.

### Usage

    splinek(x, k = 0, predict.points = NULL)

### Arguments

`x` | A numeric vector.
`k` | The number of equally spaced knot points for a cubic smoothing spline. If zero (the default) or omitted, `k` is set to `asreml.options()$knots`, in which case the number of knot points used will be `min(unique(x), asreml.options()$knots)`.
`predict.points` | An optional vector of points to be included in the design matrix for prediction.

### Value

A list including the following components:

knotpoints

  The knot points generated by `ASReml`.

zknots

  The spline design matrix at the knot points.
