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.
gp list of gpar objects used for the drawing the tiles.
