table.cont: Plot of Contingency Tables

Description

presents a graph for viewing contingency tables.

Usage

table.cont(df, x = 1:ncol(df), y = 1:nrow(df),
    row.labels = row.names(df), col.labels = names(df),
    clabel.row = 1, clabel.col = 1, abmean.x = FALSE, abline.x = FALSE,
    abmean.y = FALSE, abline.y = FALSE, csize = 1, clegend = 0, grid = TRUE)

Arguments

df

a data frame with only positive or null values

x

a vector of values to position the columns

y

a vector of values to position the rows

row.labels

a character vector for the row labels

col.labels

a character vetor for the column labels

clabel.row

a character size for the row labels

clabel.col

a character size for the column labels

abmean.x

a logical value indicating whether the column conditional means should be drawn

abline.x

a logical value indicating whether the regression line of y onto x should be plotted

abmean.y

a logical value indicating whether the row conditional means should be drawn

abline.y

a logical value indicating whether the regression line of x onto y should be plotted

csize

a coefficient for the square size of the values

clegend

if not NULL, a character size for the legend used with par("cex")*clegend

grid

a logical value indicating whether a grid in the background of the plot should be drawn
