struc_sieve: 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"), gp_tile = gpar(),
scale = 1)

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.

split_vertical

vector of logicals indicating, for each dimension of the table, the split direction.

Arguments

sievetype

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

gp_tile

object of class "gpar", controlling the appearance of all static elements of the cells (e.g., border and fill color).

scale

Scaling factor for the sieve.

Details

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