Very good question. Such customization would be a minimal
requirement for me to use it personally.
My 2014 (last year)'s useR! plenary talk
"Good Practices in R Programming"
(e.g. from here http://stat.ethz.ch/Teaching/maechler/R/useR_2014/)
tried to emphasize (among too many other things) that good programming
style includes consistency, and at least orally I did mention style guides,
*but* that good style by an expert human is clearly superior to any
blindly enforced rules, in the same way that good programming is not only
something you do by rules, but is partly an art.
In addition: R stands on the shoulders of S and a long very successful
history which unfortunately includes inconsistent (function, variable,
argument, ..) names that have belonged the language "forever".
So, I would hate that a specific style guide is used (as in lintr) to
define what is undesirable style and even prevent me doing better than
a machine-enforced ruleset.
