epitab - Contingency Tables in R

I’ve just released a new package onto CRAN and while it doesn’t perform any complex calculations or fit a statistical niche, it may be one of the most useful everyday libraries I’ll write. In short, epitab provides a framework for building descriptive tables by extending contingency tables with additional functionality. I initially developed it for my work in epidemiology, as I kept coming across situations where I wanted to programmatically generate tables containing various descriptive statistics to facilitate reproducible research, but I could not find any existing software that met my requirements.
