## Core-generating Function for Sieve Plots

### Description

Core-generating function for `strucplot` returning a function producing sieve plots.

### Usage

    struc_sieve(sievetype = c("observed","expected"))

### Arguments

`sievetype` | logical indicating whether rectangles should be filled according to `observed` or `expected` frequencies.

### Details

This function is usually called by `strucplot` (typically when called by `sieve`) and returns a function used by `strucplot` to produce sieve plots.

### Value

A function with arguments:

`residuals` | table of residuals.
`observed` | table of observed values.
`expected` | not used by `struc_sieve`.
`spacing` | object of class `"unit"` specifying the space between the tiles.
