In eeptools: Convenience Functions for Education Data

Draw a visual crosstab (mosaic plot) with shading for correlations and labels in each cell.

Description

Improves labeling of mosaic plots over mosaic from the vcd package

Usage

crosstabplot(
  data,
  rowvar,
  colvar,
  varnames,
  title = NULL,
  subtitle = NULL,
  label = FALSE,
  shade = TRUE,
  ...
)

Arguments

data	a data object, matrix or dataframe, that contains the categorical variables to compose the crosstab
rowvar	a character value for the column in data that will be displayed on the rows of the crosstab
colvar	a character value for the column in data that will be displayed in columns of the crosstab
varnames	a character vector of length two with the labels for rowvar and colvar respectively
title	a character vector of length one that contains the main title for the plot
subtitle	a character vector of length one that contains the subtitle displayed beneath the plot
label	logical, if TRUE cells will be labeled, else they will not
shade	logical, if TRUE cells will be shaded with Pearson residuals
...	additional arguments to crosstabs e.g. digits

Value

A mosaic plot

mosaic which this function wraps crosstabs which does the data manipulation for the crosstab

Examples

df <- data.frame(cbind(x=seq(1,3,by=1), y=sample(LETTERS[6:8],60,replace=TRUE)),
fac=sample(LETTERS[1:4], 60, replace=TRUE))
varnames<-c('Quality','Grade')
myCT <- crosstabs(df, rowvar = "x",colvar = "fac", varnames = varnames, digits =2)
crosstabplot(df, rowvar = "x",colvar = "fac", varnames = varnames, 
title = 'My Plot', subtitle = 'Foo', label = FALSE, shade = TRUE, digits = 3)
