Off-diagonal Panel Functions for Table Pairs Plot

Description

Off-diagonal panel functions for pairs.table.

Usage

pairs_strucplot(panel = mosaic, 
  type = c("pairwise", "total", "conditional", "joint"),
  legend = FALSE, margins = c(0, 0, 0, 0), labeling = NULL,
  shade = FALSE, ...)
pairs_assoc(...)
pairs_mosaic(...)

Arguments

panel function to be used for the plots in each cell—currently, assoc and mosaic are available.
type character string specifying the type of independence model visualized in the cells.
legend logical specifying whether a legend should be displayed in the cells or not.
margins margins inside each cell (see strucplot).
labeling labeling function or labeling-generating function (see strucplot).
shade shading function or shading-generating function (see strucplot).
... pairs_mosaic and pairs_assoc: parameters passed to pairs_assocplot. pairs_assocplot: other parameters passed to panel function.

Details

These functions really just wrap assoc and mosaic by basically inhibiting labeling and legend-drawing and setting the margins to 0.

Value

A function with arguments:

x contingency table.
i,j cell coordiantes.
