PlotXTabs: Plot a Cross Tabulation of two variables using dplyr and ggplot2

Description

Takes a dataframe and at least two variables as input, conducts a crosstabulation of the variables using dplyr. Removes NAs and then plots the results as one of three types of bar (column) graphs using ggplot2. The function accepts either bare variable names or column numbers as input (see examples for the possibilities)

Usage

PlotXTabs(dataframe, xwhich, ywhich, plottype = "side")

Arguments

dataframe

an object that is of class dataframe

xwhich

either a bare variable name that is valid in the dataframe or one or more column numbers. An attempt will be made to coerce the variable to a factor but odd plots will occur if you pass it a variable that is by rights continuous in nature.

ywhich

either a bare variable name that is valid in the dataframe or one or more column numbers that exist in the dataframe. An attempt will be made to coerce the variable to a factor but odd plots will occur if you pass it a variable that is by rights continuous in nature.

plottype

one of three options "side", "stack" or "percent"

Value

One or more ggplots to the default graphics device as well as advisory information in the console

PlotXTabs(mtcars, am, vs, "stack")
PlotXTabs(mtcars, am, vs, "percent")
PlotXTabs(mtcars, am, 8, "side")

PlotXTabs(mtcars, am, c(8,10), "percent")
PlotXTabs(mtcars, c(10,8), am)
PlotXTabs(mtcars, c(2,9), c(10,8), "mispelled")
# }
# NOT RUN {
PlotXTabs(happy,happy,sex) # baseline
PlotXTabs(happy,2,5,"stack") # same thing using column numbers
PlotXTabs(happy, 2, c(5:9), plottype = "percent") # multiple columns RHS
PlotXTabs(happy, c(2,5), 9, plottype = "side") # multiple columns LHS
PlotXTabs(happy, c(2,5), c(6:9), plottype = "percent")
PlotXTabs(happy, happy, c(6,7,9), plottype = "percent")
PlotXTabs(happy, c(6,7,9), happy, plottype = "percent")
