R: Compute scaling functions on internally predefined grid

ScalingFunction {wavethresh} | R Documentation

## Compute scaling functions on internally predefined grid

### Description

This is a subsidiary routine not intended to be called by a user: use `draw` instead. Generates scaling functions by inserting a Kronecker delta function into the bottom of the inverse DWT and repeating the inverting steps.

### Usage

    ScalingFunction(filter.number = 10, family = "DaubLeAsymm", resolution = 4096,
        itlevels = 50)

### Arguments

`filter.number` | The filter number of the associated wavelet. See `filter.select`
`family` | The family of the associated wavelet. See `filter.select`
`resolution` | The nominal resolution, the actual grid size might be larger than this
`itlevels` | The number of complete filtering operations to generate the answer

### Details

Description says all

### Value

A list containing the `x` and `y` values of the required scaling function.
