[R] Programming Concepts and Philosophy

I am wondering if people on the list could recommend books that they have found helpful about programming concepts and style? I often find that students write R programs by copying existing code but could really benefit from the understanding of more general programming ideas. An example would be to avoid writing functions which attempt to modify their parameters. Another principle would be not to write programs with numbers used as constants but to assign them to named objects as in

n <- 120 # number of observations
p <- 10 # number of variables

near the beginning of a program rather than using "10" and "120" throughout the script.

This sort of stuff is not specifically R but can be a problem for students with little programming background.

I am happy to summarise responses.
