Contingency tables are useful short hand ways of inputting and visualizing data. I have yet to find an easy way to convert between contingency tables and data frames in R. Below is a short script in which I input a contingency table, create a function to convert the 2 by 2 table to a data frame, and convert the data frame back to a table. These operations are useful for running some statistical operations that either only work on tables or only work on data frames. Hope the below example is useful.
