By the way, does anybody knows if there is a R tidy or some similar
project to automatically reformat (and possibly check) R code, beside
what Emacs does?
See the appropriate section in `Writing R Extensions' (3.1 `Tidying R

Hello,
About the R style war: as soon as you write code for yourself, you can
do what you want, of course. If your code is shared (for instance, code
in packages submitted to CRAN), it makes sense to render it so that it
is easier to read *by a majority of people*. The only way to make sure
