[R] R is GNU S, not C.... [was "how to get or store ....."]

I consistently use ";" at every end of my R code and have found it much more
neat than those sentences without an end; for "<-" and "=", if I were the
author I would rather take the first representation as a sign of
passing-by-reference while the latter by value.

However, as the author Henrik Bengtsson points out "these guidelines are
ours and not the R-developers." Perhaps a definitive style guide published
by R core that ensured consistency among new base code would be a helpful
addition. I personally find the above style guide extremely useful when
multiple programmers work on the same project, and would welcome a formal
endorsement or revision by the R developers. (And despite Henrik's elegant
guide, I too leave off the semicolons at the end of the lines.)
