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.
