Fourfold Display
data: 2x2xk contingency tableslibrary: vcdfunction: fourfoldplot
Description
The fourfold display depicts frequencies by quarter circles, whose radius is proportional to nij , so thearea is proportional to the cell count . The cell frequencies are usually scaled to equate the marginaltotals, and so that the ratio of diagonally opposite segments depicts the odds ratio. Confidence rings forthe observed odd ratio allow a visual test of the hypothesis H0 : = 1 corresponding to no association.They have the property that the rings for adjacent quadrants overlap iff the observed counts are consistentwith the null hypothesis.

Mosaicplot - Associations in a contingency table
variables: QL ( 2)library: -function: mosaicplot
Description
Mosaicplot graph represents a contingency table, each cell corresponding to a piece of the plot, whichsize is proportional to cell entry.
Extended mosaic displays show the standardized residuals of a loglinear model of the counts from bythe color and outline of the mosaics tiles. (Standardized residuals are often referred to a standard normaldistribution.) Negative residuals are drawn in shaded of red and with broken outlines; positive ones aredrawn in blue with solid outlines.
Thus, mosaicplot are perfect to visualize associations within a table and to detect cells which createdependancies.

Tukeys Hanging Rootogram
variables: 1 QLlibrary: vcdfunction: rootogram
Description
Discrete frequency distributions are often graphed as histograms, with a theoretical fitted distributionsuperimposed. It is hard to compare the observed and fitted frequencies visually, because (a) we mustassess deviations against a curvilinear relation, and (b) the largest frequencies dominate the display.
The hanging rootogram (Tukey, 1977) solves these problems by (a) shifting the histogram bars tocoincide with the fitted curve, so that deviations may be judged by deviations from a horizontal line, and(b) plotting on a square-root scale, so that smaller frequencies are emphasized. Featured example showsmore clearly that the observed frequencies differ systematically from those predicted under a Poissonmodel.
