- echo, print.eval
The files in
contain R code for all examples and figures in the book.
The examples can all be directly executed by the user.
The code examples all use these functions.
The versions of these functions here are essentially placeholders.
hhdev.off are no-ops and return
As a consequence, the code between them will execute and display on

hhlatex prints the latex source to the
console and returns
While writing the book, these placeholder functions are replaced by more elaborate functions with the same names that write the graphs onto pdf or png files, the console output to text files, and the latex code to a file.
