ABSTRACT
When you have your data cleaned and organized you will begin to examine it with statistical analyses. In this book we don’t look at how to do statistical analysis in R (a subject that would and does take up many books). Instead we focus on how to make your analyses really reproducible. To do this you dynamically connect your data gathering and analysis source code to your presentation documents. When you dynamically connect your data gathering makefiles and analysis source code to your markup document you will be able to completely rerun your data gathering and analysis and present the results whenever you compile the presentation documents. Doing this makes it very clear how you found the results that you are advertising. It also automatically keeps the presentation of your results-including tables and figures-up-to-date with any changes you make to your data and analyses source code files.
